Rebels - S1E9 - "Path of the Jedi"

7:33 - Kanan (to Ezra):  "Good luck."  In The Empire Strikes Back, an unidentified Rebel pilot wishes Luke good luck [36:02] and Luke wishes Lando good luck [2:00:09], and in Return of the Jedi, Han and Lando wish each other good luck [Han to Lando at 50:33 and Lando to Han at 52:21].

14:02 - Ezra:  "I'm not afraid."  Luke also says this in The Empire Strikes Back [57:22].

15:12 - Yoda (to Kanan):  "Patience."  In The Empire Strikes Back, Yoda and Obi-Wan also counsel Luke with, "Patience!" [Yoda at 54:36 and 55:03; Obi-Wan at 1:24:18], and in Return of the Jedi, the Emperor advises Vader:  "Patience, my friend" [38:57].  It's also part of Obi-Wan's advice to Anakin in Attack of the Clones:  "Patience.  Use the Force.  Think." [21:49].  Also in Attack of the Clones, Dooku, referring to Padmé, tells Gunray, "Patience, Viceroy, patience; she will die" [1:49:27].

17:38 - Yoda (to Ezra):  "Tell me, why must you become Jedi?"  He asks Luke nearly the same question in The Empire Strikes Back:  "Why wish you become Jedi?" [55:12]

20:39 - Zeb (about Ezra and his lightsaber):  "He's been working on that thing for weeks."  One of the kids in The Phantom Menace makes a similar comment about Anakin's podracer:  "You've been working on that thing for years" [48:09].
