0:56 - Rex (to Anakin): "Sir, we are at the rendezvous point, and there's no sign of you on our scanners." Luke also uses this expression during the Battle of Yavin at the end of A New Hope; after Red Ten asks Luke if he sees any fighters, Luke replies, "No sign of any- wait, comin' in point three five" [1:51:59].
0:59 - Anakin: "Oh, come on. That's impossible. Something's wrong. We're at the exact coordinates where the distress signal originated, but there's nothing here. Rex is at the exact same coordinates, and he's not here." In The Empire Strikes Back, Luke also says, "That's impossible" [1:51:21].
1:21 - Obi-Wan (after the shuttle loses power): "Not good."
Ahsoka: "Everything's dead, even the life support."
These lines have some similarity to what Anakin says to R2 after they land in the droid control ship in The Phantom Menace: "Everything's overheated. Oops, this is not good." [1:58:57].
2:01 - Obi-Wan: "Everyone strap yourselves in." Han Solo uses this same expression in A New Hope: "Go strap yourselves in; I'm gonna make the jump to lightspeed" [56:46].
3:49 - Obi-Wan (in response to Anakin's asking if Obi-Wan or Ahsoka heard Daughter speaking): "I didn't hear anything." In The Phantom Menace, Qui-Gon has a similarly dismissive "I don't sense anything" [3:07] in response to Obi-Wan's bad feeling. The resemblance here, which is probably just coincidental, is more in the delivery than specific diction. At 3:28, Obi-Wan says, "I don't see anything" after Ahsoka points out a reflection, but this is said in a different manner.
3:57 - Anakin (to Daughter): "Who are you?" This too is probably just coincidental, but in The Phantom Menace, Jar Jar Binks has essentially the same line ("Whosa are yousa?" [29:00]) delivered with equal stresses on "Whosa" and "yousa," which is the same way Anakin says it here.
5:59 - Obi-Wan (to Anakin): "Are you alright?" In The Phantom Menace, Anakin asks Qui-Gon, "Are you alright?" [1:17:31]. In Attack of the Clones, Padmé asks Anakin, "Ani, are you alright?" [50:02], and later a clone trooper asks Padmé, "Are you alright?" [2:05:54]. In Revenge of the Sith, Anakin asks the Chancellor, "Are you alright?"[11:49], and a bit later, Mace Windu asks him, "Chancellor Palpatine, are you alright?" [24:53]. Padmé also asks Anakin, "Are you alright?" [1:27:59]. In A New Hope, Luke asks Obi-Wan this [59:16] and Biggs asks Luke [1:46:44], and in The Empire Strikes Back, Luke asks, "Rogue Two, are you alright?" [30:31]. Luke also asks Han, "Are you alright?" when they're captured by Jabba in Return of the Jedi [28:31].
6:08 - Anakin (to Obi-Wan, referring to the Daughter): "I'll follow her and find out how to get off this rock." Luke uses the same expression in A New Hope; after C-3PO asks if there's anything he can do to help, he replies, "Not unless you can alter time, speed up the harvest, or teleport me off this rock" [19:58].
7:48 - Obi-Wan (after Ahsoka asks what the Brother was): "I'm not quite sure." In A New Hope, after Luke sees R2-D2's message and asks who Leia is, C-3PO gives basically the same response: "I'm afraid I'm not quite sure, sir" [21:35].
