The Clone Wars - S2E16 - "Cat and Mouse"

0:58 - Anakin:  "Master Kenobi better get here soon or this is gonna be one short rescue mission."  This bears some similarity to what Han Solo says in A New Hope (also referring to Obi-Wan):  "I hope that old man got that tractor beam out of commission or this is gonna be a real short trip" [1:32:55].

3:33 - Admiral Trench:  "I have won this round."  Perhaps coincidentally, Padmé uses this same phrase in The Phantom Menace, referring to the Trade Federation battle droids:  "They win this round" [1:58:17].

5:08 - Obi-Wan (to Anakin):  "I need you to run a mercy mission down to the planet's surface" and a bit later (5:26):  "I need you to continue the mercy mission."  Darth Vader also uses the phrase "mercy mission" in A New Hope when he says to Leia, "You weren't on any mercy mission this time" [7:47].

11:48 - Bail Organa:  "Help us, General Kenobi; you're our only hope."  Obviously, this echoes Leia's line "Help me, Obi-Wan Kenobi; you're my only hope" in A New Hope [35:35], but this whole episode is also an example of what she refers to at the beginning of her message:  "General Kenobi, years ago, you served my father in the Clone Wars..." [35:05].

17:04 - Trench: "And your friends on the planet below shall perish as a result of your failure."  This has some resemblance to what Palpatine says to Luke in Return of the Jedi:  "And your friends on the Endor moon will not survive" [1:44:25].

18:18 - Anakin:  "Well, no ship this small usually has a cloaking device."  Captain Needa has a similar line, referring to the Millennium Falcon, in The Empire Strikes Back:  "No ship that small has a cloaking device" [1:07:49].
