The Clone Wars - S3E15 - "Overlords"

Throughout the scene in "Overlords" where Anakin uses the Force to compel the Daughter and the Son to release Obi-Wan and Ahsoka, he uses his left, biological arm to control the Daughter (who represents the light side) and his right, mechanical arm to control the Son (who represents the dark side).

This arrangement has some significance.  At the very least, it foreshadows the association between artificial limbs and the dark side of the Force that Anakin will exhibit as Darth Vader.  In a comment to Luke in Return of the Jedi, Obi-Wan mentions this connection:  "He's more machine now than man, twisted and evil."

(The different qualities of Anakin's arms also hold significance in a scene in "Crisis at the Heart" [S6E7], which I've written about here.)

The Clone Wars - S1E1 - "Ambush"

When Lama Su gives Obi-Wan a tour of the cloning facility in Attack of the Clones, he explains, "Clones can think creatively.  You will find that they are immensely superior to droids."  This ability to "think creatively" is subtly demonstrated by Lieutenant Thire in "Ambush."

Roughly halfway through the episode, as Yoda and his squad of clone troopers retreat from a group of destroyer droids, Yoda deflects the droids' blaster fire into a coral branch that then falls on the droids and crushes them.  Later, when Yoda is holding off an-other group of destroyer droids by himself, Thire uses the same sort of technique:  he fires the clones' one remaining rocket at a cliff so that it explodes and the resulting rubble falls on the droids.  He paid attention to Yoda's strategy (taking advantage of his environment) and was then able to adapt it to his own circumstances.

The Clone Wars - S6E10 - "The Lost One"

In "The Lost One," when Yoda goes to see Chancellor Palpatine about a file on Sifo-Dyas that has been sealed by the office of the Supreme Chancellor, Palpatine's shadow falls on Yoda for most of their conversation:

That Palpatine's shadow falls where it does illustrates Palpatine's deception of Yoda and the Jedi in general.  He's obscuring the Jedi's vision so that they don't discover his other identity as Darth Sidious.

The Clone Wars - S6E7 - "Crisis at the Heart"

Near the end of "Crisis at the Heart," a droid starfighter shot down by a clone pilot crashes into the office where Clovis is desperately trying to convince Anakin and Padmé that it's Count Dooku who's deceiving them, not Clovis himself.  The office is at the top of a tower, which starts to tilt because of the damage it's sustained.  Anakin catches both Padmé and Clovis as they slide off the edge:

Significantly, he's holding Padmé with his remaining human arm (his left arm) and Clovis with his artificial arm (his right arm):

The arms with which he's holding these two characters illustrate the different type of connection he has with each.  He has a very close relationship with Padmé, so he's holding her with his remaining human arm.  On the other hand (literally), he hasn't trusted Clovis throughout this arc of episodes (thinking he's too involved with the Separatists), so while he's holding him too, it's with his artificial arm, which symbolizes that distance between them.

The Clone Wars - S6E6 - "The Rise of Clovis"

In "The Rise of Clovis," after Clovis repeatedly asks about the relationship between Padmé and Anakin, Padmé asserts that "there is nothing romantic between he and I."  The pronouns "he" and "I" are in the wrong grammatical case here; they should be "him" and "me."  Presumably, as a senator, Padmé has a quality education and wouldn't normally make such a mistake, but her misuse of these pronouns indicates that she's flustered because of Clovis's suspicion - or perhaps even discernment - of the romantic relationship that does indeed exist between the two.  It's also significant that Padmé separates herself from Anakin here; she says, "he and I" and not "us."

The Clone Wars - S6E3 - "Fugitive"

Throughout "Fugitive," AZ-3's mouth lights up when he's speaking, so in other words, a lit mouth is an open mouth.

After Fives becomes convinced that, like Tup, there's a chip inside his own head, he tells AZ, "You have to take it out."  AZ is hesitant and tells Fives that it's a "dangerous surgery" and "you may die," but Fives replies, "It's a chance I have to take.  I trust you."  Before finally agreeing, AZ's mouth lights up without his saying anything and stays lit for a few seconds.  This is the droid equivalent of his mouth hanging open in surprise.

The Clone Wars - S5E19 - "To Catch a Jedi"

Near the end of "To Catch a Jedi," Barriss Offee (whose identity isn't revealed until the next episode) steals Asajj Ventress's mask and lightsabers and, disguised as Ventress, attacks Ahsoka Tano.  During the fight, she slashes a pipe so that the resulting exhaust temporarily stuns Ahsoka.

While this is somewhat similar to an event in The Empire Strikes Back, where Luke directs exhaust from a cut hose in the carbon freezing chamber at Vader, creating enough of a distraction so that he can retrieve his fallen lightsaber, it actually has a closer analogue in an earlier episode of The Clone Wars, and this holds greater significance.

In "Cloak of Darkness" (S1E9), there's a lightsaber duel between Luminara Unduli and Asajj Ventress in which Ventress does the same thing:  she cuts a pipe in the Jedi cruiser so that the steam compromises Luminara's vision.  Ahsoka was present at the duel (albeit the later stages), and since Barriss is Luminara's padawan, it's likely that she's familiar with it, too.  In "To Catch a Jedi," she adopts this move as an-other facet of her disguise and an-other way to make Ahsoka believe that she is Ventress.

The Clone Wars - S5E16 - "The Lawless"

During Obi-Wan Kenobi's escape from Mandalore in "The Lawless," he and a group of Mandalorians encounter a giant, closed door.  As it opens, the camera angle tilts.  At first, the camera is level with the ground:

But as the shot goes on, the camera shifts so that everything is at an angle:

The shot as a whole illustrates the civil war that has beset Mandalore.  Previously, there had been stability, but now there is confusion.  Along with this shifting camera angle, the chaos is illustrated in the background, where Mandalorians are fighting each other and there are various blaster shots and explosions.

The Clone Wars - S4E15 - "Deception"

In "Deception," after Moralo Eval, Cad Bane, and Rako Hardeen (Obi-Wan Kenobi in disguise) have escaped from prison, they steal a police speeder to get to the docks to steal a ship and leave Coruscant.  Moralo Eval and Cad Bane take the front seats, leaving the back seat for Rako Hardeen:

Since this is a police speeder and the back seat is where criminals are detained, there are bars in the interior and on the canopy.  Visually, this represents Kenobi's situation.  His goal is to investigate a kidnapping threat against Chancellor Palpatine that Eval is allegedly involved with, and for the moment, he simply has to go along with Eval's plans in order to discover more information.  In the same way that he experiences this temporary lack of agency, he's confined in the prisoner's seat of the police speeder.

The Clone Wars - S3E1 - "Clone Cadets"

"Clone Cadets" follows a particular squad of clone troopers (Domino Squad) who are having trouble working together.  While watching the squad perform poorly in a training session, Shaak Ti remarks, "The one they call Echo never adapts to the situation," and the bounty hunter El-Les, who is helping the Jedi train the clones, comments, "CT-782 seems to follow his own path.  He can't do it all alone."  Two other clones argue with each other too much and are shot down by training droids, and the last clone surrenders when he's surrounded.  Shaak Ti then summarizes the squad's problem:  "If these cadets can't get past their short-sighted selfishness, they will never come together.  Unity wins war, gentlemen."

Later in the episode, Commander Colt comes to watch a few squads perform their final tests.  The squads meet him in a hangar, and after Bravo Squad is chosen as the first squad to run the simulation, the clones file out of the hangar.  As each squad turns in formation, the clones stomp their feet, but while the clones in the other squads all stomp their feet simultaneously, the clones of Domino Squad stomp their feet at different times.  In the shot, they're shown from the waist up, so it's easier to hear the various footfalls than see them.

This detail shows that the clones are still a bit too independent and aren't yet working together.

The Clone Wars - S2E15 - "Senate Murders"

The climactic scene of "Senate Murders" features some significant lighting.

Lieutenant Divo suspects Senator Burtoni for the murders of Senator Farr and Senator Deechi, partially because the poison that killed Farr was developed by Kaminoans and Burtoni is a Kaminoan.  When Divo mentions that the poison affects only Rodians, however, Senator Amidala notes an inconsistency:  if the poison affects Rodians and the senatorial party all drank the poisoned drinks, Lolo would have been poisoned too.  As Amidala is considering this, Lolo is standing behind her, covered by her shadow:

As Amidala remembers that Lolo didn't drink, Lolo steps out from behind her, pulls a blaster on Amidala, and admits to the murders:

Lolo's standing in the shadow here represents two things.  On a simple level, it shows that she's trying to avoid the scrutiny of the investigation, but, more metaphorically, it also illustrates that her involvement has been obscured while Divo has been conducting his investigation and Amidala and Senator Organa have been doing their own.  None of them considered Lolo as a suspect until this moment, and when she steps out into the light, she reveals everything.  The shadow she's hiding in represents the characters' ignorance.

The Clone Wars - S2E14 - "Duchess of Mandalore"

In "Duchess of Mandalore," Duchess Satine doesn't accept the helping hand that one of her guards extends to her as she gets into her speeder, and this is a significant detail.

Satine's not accepting her guard's help visually illustrates how extreme her independence has become.  Later, Obi-Wan confronts her about this:  "You need your friends with you, not held at arm's length.  In your quest to be self-reliant have you decided to cut your friends out of your life?"

The Clone Wars - S2E13 - "Voyage of Temptation"

For most of "Voyage of Temptation," Duchess Satine is wearing an elaborate headdress:

When Tal Merrick* takes her hostage, however, he knocks her headdress off:

When it appears as if Merrick is going to escape with her as his prisoner, Satine confesses her love for Obi-Wan:  "Obi-Wan, it looks like I may never see you again.  I don't know quite how to say this, but I've loved you from the moment you came to my aid all those years ago."

Satine's headdress represents the hidden nature of her feelings.  Only after it's been dislodged are they exposed.

---

*There's some discrepancy in how Merrick's name is spelt.  In the credits, it's Merrick, but on the Star Wars website, it's Merrik.

The Clone Wars - S1E22 - Hostage Crisis

When Anakin gives Padmé his lightsaber in "Hostage Crisis" to prove his love for her, he does so in such a way that, if it were activated, the blade would impale her:

To some degree, this foreshadows the events of Revenge of the Sith where Anakin's turn to the dark side causes Padmé to lose her will to live.  Here, he comes very close to injuring her fatally.

The Clone Wars - S1E19 - "Storm over Ryloth"

In "Storm over Ryloth," when Anakin contacts the Separatist commander Mar Tuuk and feigns negotiations (claiming that "I've been ordered to surrender myself, the entire crew of this vessel, and my ship in exchange for safe passage of food and medical supplies to the people of Ryloth," although this isn't the case and only he and R2-D2 are on board), his face almost completely fills the Separatists' screen, as if to disguise the fact that there is no crew behind him.

After a scan reveals only one life form, Mar Tuuk realizes that this is a trick and confronts him:  "Skywalker, what treachery is this!?  You have nothing to bargain with!"  He replies, "Heh, in that case, I'll be going.  Oh, you can still have my ship," and as he speaks, he steps backwards.  Since his ruse has been discovered, he no longer needs to hide the fact that his cruiser is empty.

The Clone Wars - S1E15 - "Trespass"

In "Trespass," Chairman Cho and Senator Chuchi constrast in how they perceive and deal with the Talz.  After dead clone troopers are found in the Republic base on Orto Plutonia, Chairman Cho comments that "if it's not the Separatists out there, then it's a malevolent and aggressive enemy nonetheless."  He repeatedly calls the Talz "savages," and when he meets with Thi-Sen, he makes accusatory gestures and declares war.

During this same meeting, Senator Chuchi tries to intercede on behalf of the Talz and even steps between Cho and Thi-Sen.  Her efforts are of no avail here, but after she receives authority from the Speaker of the Assembly to make peace with the Talz, she negotiates with Thi-Sen herself.  Instead of Cho's aggressive posture, hers is a welcoming one.

It's also significant that she takes the slain chairman's hat and places it upon one of the Talz' spears.  Earlier in the episode, this same sort of monument to the Talz' victory is shown with clone helmets and droid heads:

That Chuchi does this with the chairman's hat illustrates that she understands and respects the Talz' culture, unlike Cho who considers them "little more than animals."  At the end of her negotiations, she tells Thi-Sen that she "recognize[s] your sovereignty as a free and equal people."

---

The title of the episode is ambiguous in a couple ways.  When Obi-Wan tells Chairman Cho about the Talz, Cho is indignant and says, "They're trespassers," but from the Talz' point of view, it's the Pantorans who are trespassers.

As a synonym for transgression, the title could also apply to Chairman Cho's actions, which are deemed "out of order" by the Pantoran Assembly.

The Clone Wars - S1E9 - "Cloak of Darkness"

Early in the fight between Captain Argyus and Commander Gree in "Cloak of Darkness," Argyus kicks Gree, dislodging his helmet.  The remainder of the fight is between a helmeted Argyus and a helmet-less Gree:

Their respective head gear reveals their characters.  Argyus is the leader of the senate commandos, but he's betrayed the Republic and is helping Nute Gunray escape.  He seems more concerned with himself than either side of the war though, telling Gree that he wanted "a life with more than empty servitude" and gloating to Gunray after a successful escape that "I'll be a legend for this."  His shifting loyalty is represented by his retaining his helmet, which obscures his face:

Gree, on the other hand, is steadfastly loyal to the Republic.  When Gunray tries to bribe him at the beginning of the episode (saying "I am a man of great wealth, and I can be very generous to my allies"), he doesn't even consider it, and he's indignant about Argyus' betraying the Republic.  There's no deception with Gree, which is represented by his not wearing a helmet here.  He's not hiding anything.

As far as their positions, Argyus and Gree are parallel characters.  Argyus is a captain, and Gree is a commander.  By the end of this episode, their character arcs reveal the value of their choices.  Gree has a virtuous morality and survives the incident, but Argyus, who seems concerned with only his own interests, is killed by Ventress:

The Clone Wars - S6E13 - "Sacrifice"

13:18 - Anakin (to Yoda):  "We intercepted a transmission calling Dooku to Coruscant."  This line contains the same words that are used in Vader's interrogation of Captain Antilles in A New Hope [5:44].  Vader asks, "Where are those transmissions you intercepted?  What have you done with those plans?" to which Antilles replies, "We intercepted no transmissions."

15:10 - Anakin's encounter with Dooku ends the same way as that in Revenge of the Sith, although the framing doesn't quite match:

19:30 - Force priestess:  "There is another Skywalker."  In Return of the Jedi, Yoda says this to Luke [44:25].

---

At 20:54, there's a musical cue of Yoda's theme.

The Clone Wars - S6E12 - "Destiny"

The fortune cookie is "Death is just the beginning."  Probably just coincidentally, this is similar to what Dooku says near the end of his duel with Yoda in Attack of the Clones:  "This is just the beginning" [2:09:49].

4:55 - Force Priestess (Serenity):  "We have been waiting for you, Master Yoda."  Vader greets Obi-Wan the same way in A New Hope:  "I've been waiting for you, Obi-Wan" [1:30:09].

---

Starting at 15:10 there's a musical cue of "Battle of the Heroes" from Revenge of the Sith.

The Clone Wars - S6E11 - "Voices"

3:02 - Mace Windu (to Obi-Wan, about Yoda):  "We must keep an eye on our old friend."  The phrase "old friend" is also used in Attack of the Clones (where Palpatine suggests "an old friend, like Master Kenobi" to protect Padmé [6:34] and Count Dooku calls Mace Windu "my old Jedi friend" [1:50:24] and just "old friend" [1:56:05]), in Revenge of the Sith (where Obi-Wan says, "Goodbye, old friend" to Anakin as he leaves for Utapau [51:13] and Yoda refers to Qui-Gon as "an old friend" [2:09:56]), in A New Hope (where Leia sarcastically says, "We, uh, ran into some old friends" when Han asks her and Luke where they've been [1:31:33]), in The Empire Strikes Back (where Yoda says that through the Force, Luke will see "Old friends long gone" [1:17:05]), and in Return of the Jedi (where Luke says, "I have a promise to keep to an old friend" [37:37] and Han calls C-3PO "an old friend of mine" [1:11:53]).

4:37 - Yoda:  "Rest I need.  Yes, rest."  He also says this to Luke in Return of the Jedi [42:02], and the context is similar, too:  both times he's trying to evade the conversation.  Here, he's trying to avoid talking to Anakin about Qui-Gon Jinn's contacting him through the Force, and in Return of the Jedi, he's trying to avoid revealing Vader's true identity to Luke.

6:57 - Rig Nema: "I am not an expert on his biology, but from my point of view, he is in perfect health."  In Revenge of the Sith, Anakin says (to Obi-Wan):  "From my point of view, the Jedi are evil" [1:58:33], and in Return of the Jedi, Obi-Wan justifies himself to Luke by claiming that what he said was true "from a certain point of view" [46:23].

9:46 - Anakin (referring to the induced meditation procedure Yoda is undergoing):  "I don't like this."  This is also Leia's reaction after the Millennium Falcon lands in Cloud City in The Empire Strikes Back [1:19:58].

10:33 - Obi-Wan (to Yoda, after he's out of the induced meditation):  "Welcome back, old friend."  An-other use of "old friend."

10:38 - Yoda:  "Speaking to the dead I was, friends long gone, good friends."  He also uses this description while training Luke in The Empire Strikes Back:  "Through the Force, things you will see, other places, the future, the past, old friends long gone" [1:16:58].

15:22 - Qui-Gon:  "Yoda, my old friend, you have come at last."  Yet an-other "old friend."

---

At 2:54, 15:45, and 17:16, there are brief musical cues of Yoda's theme from The Empire Strikes Back, and at 19:40, as Yoda talks about darkness and evil, there's a brief cue of the Imperial march.
