Rebels - S2E16 - "Homecoming"

5:19 - Cham:  "If you gave me half the attention you gave this second rate junk pile, we'd have liberated Ryloth by now."  In A New Hope, C-3PO similarly insults R2-D2 and calls him a "nearsighted scrap pile" [9:56].  More generally, this comment resembles what Obi-Wan says to Anakin in Attack of the Clones:  "If you spent as much time practicing your saber techniques as you do your wit, you would rival Master Yoda as a swordsman" [16:30].

8:26 - Imperial officer:  "Proceed to bay two.  We'll cover you."  Luke's comments to Red Leader in A New Hope have the same structure:  "Turn to point oh five.  We'll cover for you." [1:53:02].

11:10 - Zeb (after Sabine says that all Ryloth would see the fireball if the carrier explodes):  "I think that's the idea."  According to the subtitles, Greedo uses this expression in A New Hope; after Han says, "Over my dead body," Greedo replies in Huttese, "That's the idea" [50:44].

11:47 - Zeb (after Sabine points out stormtroopers he can shoot):  "That'll do."  Anakin also says this in Attack of the Clones after Padmé points out a spot to land on Geonosis [1:35:40], and Han makes a similar comment, also about a landing spot, in The Empire Strikes Back:  "Yeah, that'll do nicely" [40:11].

12:22 - Stormrooper:  "Close the blast doors!"  A stormtrooper also says this in A New Hope [1:29:39], and Nute Gunray says it in The Phantom Menace [6:27].

15:20 - Kanan:  "Cham, we don't have time for this."  In The Phantom Menace, Padmé says, "We don't have time for this, Captain" to Panaka while exchanging fire with battle droids [1:52:54]

20:28 - Hera (referring to the carrier):  "Alright, let's see what she can do."  In Return of the Jedi, Han says the same thing about the stolen Imperial shuttle: "Chewie, let's see what this piece of junk can do" [53:02].
