Rebels - S2E22 - "Twilight of the Apprentice - Part II"

1:49 - Kanan:  "Dealing with Inquisitors is one thing; Vader is another."  Han's comment to Obi-Wan in A New Hope is somewhat similar:  "Look, good against remotes is one thing.  Good against the living?  That's something else."  [1:02:20].  Luke also makes the same sort of comparison in The Empire Strikes Back after Yoda implies that he should use the Force to get his X-wing out of the swamp:  "Master, moving stones around is one thing; this is totally different!" [1:09:12].

3:58 - Maul (as Kanan tries to step onto the lift with Maul and Ezra):  "Only two.  No more, no less."  In The Phantom Menace, Yoda also uses this phrase to describe the Sith:  "Always two there are, no more, no less, a master and an apprentice" [2:07:59].

5:47 - Ezra (to Kanan):  "Trust me."  Han also says, "Trust me" (to Leia) in The Empire Strikes Back [1:20:06].

7:33 - Maul (to Ezra):  "Use your anger."  In Return of the Jedi, Palpatine similarly counsels Luke:  "Use your aggressive feelings, boy" [1:48:49].

7:48 - Maul (to Ezra, referring to the Seventh Sister):  "Strike her down!"  Palpatine uses this phrase in Return of the Jedi as he taunts Luke:  "Strike me down with all of your hatred, and your journey towards the dark side will be complete!" [1:45:00]

13:13 - Kanan:  "Chopper!  Am I glad to hear you!"  Luke says something similar in A New Hope:  "Ben Kenobi?  Boy, am I glad to see you!" [30:35]

19:56 - Kanan (to Ezra):  "There's nothing we can do now."  In A New Hope, Obi-Wan tells Luke something similar after he finds his aunt and uncle dead:  "There's nothing you could have done, Luke, had you been there" [42:02].
