9:47 - Kanan (to Ezra and Zeb): "We'll take the long way around." Padmé says almost the same thing in The Phantom Menace, after Darth Maul arrives and blocks the way: "We'll take the long way" [1:50:30].
10:07 - Commander Sato: "We are employing escape plan delta, Captain Syndulla." In The Empire Strikes Back, Luke announces the similarly named "Attack pattern delta" [26:44].
12:56 - Sabine (as The Ghost is closing on the tractor beam emitter): "Almost got it, almost got it." In A New Hope, Red Leader says something similar as he approaches the target on the Death Star: "Almost there" [once at 1:52:17 and again at 1:52:29].
13:28 - Commander Sato (once the command ship is free from the tractor beam): "Get us out of here, now!" Han also says this in A New Hope: "Chewie, get us outta here!" [55:26].
16:08 - Ezra (referring to the lothcat he's chasing): "Fast little fuzzball." Han uses the same moniker in The Empire Strikes Back when he tells Chewbacca, "Laugh it up, fuzzball" [17:26].
17:16 - Ezra: "Something familiar about this." In The Empire Strikes Back, Luke makes a similar comment about Dagobah: "There's something familiar about this place" [47:12].
17:33 - Ezra: "X-10? Hold your fire; we're friends." The context is quite different, but Obi-Wan also says this to Anakin when he tries to shoot the buzz droids off Obi-Wan's starfighter in Revenge of the Sith: "Hold your fire! You're not helping here!" [6:03]
