4:54 - Agent Kallus (to stormtrooper, about the rebels): "Move in. I'll be there soon, and, commander, I want them alive." Vader gives the same command to the stormtroopers in A New Hope ("Bring me the passengers; I want them alive!" [6:08]) and to the bounty hunters in The Empire Strikes Back ("You are free to use any methods necessary, but I want them alive, no disintegrations" [1:06:14]).
6:23 - Ezra: "Thanks, Hondo. We owe you one." In Return of the Jedi, Han also tells Luke, "I owe you one" [37:21].
17:13 - Zeb: "Trust me, Hera." Han also says, "Trust me" (to Leia) in The Empire Strikes Back [1:20:06].
20:54 - Ezra (after Zeb says the two Lasat aren't alone): "What are you talkin' about?" This line appears three times in A New Hope: twice, C-3PO asks R2-D2, "What are you talking about?" [6:51 and 9:47], and later, in response to Luke's urge to rescue Leia, Han Solo asks, "What are you talkin' about?" [1:11:03]. In Attack of the Clones, Anakin also asks Padmé, "What are you talking about?" [1:43:07].
