Zeb: "I agree."
Yoda makes a similar comment to Padmé near the beginning of Attack of the Clones: "Seeing you alive brings warm feelings to my heart" [5:33].
Yoda also says, "I agree" in Revenge of the Sith (to Ki-Adi-Mundi's suggestion that it's Obi-Wan who should confront Grievous) [49:09].
1:36 - Azmorigan (about Hera): "Oh, I remember now, the feisty one." In Return of the Jedi, EV-9D9 also describes R2-D2 this way: "You're a feisty little one" [12:04].
3:50 - Hondo (after Sabine asks why he doesn't use his own crew for salvaging): "Oh, trust me; that is a long, boring story." Hondo uses it more as an off-handed comment, but Han also says, "Trust me" (to Leia) in The Empire Strikes Back [1:20:06].
6:37 - Sabine (as the salvage operation starts): "Alright, boys, 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]. Luke also says, "Alright, boys" as the snowspeeders join the battle in The Empire Strikes Back: "Alright, boys, keep tight now" [26:38].
7:31 - Azmorigan (about a clunk): "What was that?"
Zeb: "It's nothing. It's loose cargo."
Azmorigan: "I saw something move! There!"
There's some similarity between this and Luke's discovery of the dianoga in the trash compactor in A New Hope: "Something just moved past my leg. Look! Did you see that!?" [1:19:53]
12:06 - Sabine (after Zeb warns her about the proton bombs): "I'll be careful." In the cantina in A New Hope, Luke assures Dr. Evazan that "I'll be careful" [46:46].
14:03 - Hera (to Ezra): "We're running out of time here!" Qui-Gon also says this in The Phantom Menace: "Either way, we're running out of time" [40:07].
14:05 - Ezra: "Hondo! Come on, I need your help." Queen Amidala says the same thing to Jar Jar in The Phantom Menace ("I need your help" [1:37:55]); Obi-Wan to Padmé in Revenge of the Sith ("Padmé, I need your help" [1:38:44]); and Obi-Wan to Luke in A New Hope ("I need your help, Luke. She [Leia] needs your help." [36:03]).
20:19 - Kanan: "Punch it, Hera." Han also says, "Punch it!" to Chewbacca in The Empire Strikes Back [35:35].
