7:07 - Vizago (after Mart tells him and Wolffe that Ezra gave him a special mission): "What are you talking 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 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].
24:52 - Rex (after Chopper is shocked): "Great. Now what?" Han also wonders, "Now what!?" during Princess Leia's rescue in A New Hope [1:18:11].
29:41 - Ezra (to the Emperor): "You're wrong. I have a family; I don't need anything from you." In Return of the Jedi, Luke also says, "You're wrong" to the Emperor, after the Emperor tells him that Vader and soon Luke himself cannot be turned from the darkside [1:31:52].
31:32 - Hera: "Shields up!" It's unclear whether this is a statement or a command, but both appear in The Phantom Menace. The captain of Qui-Gon and Obi-Wan's ship shouts it as a command [5:11], and Anakin says it as a comment [2:02:18].
32:06 - Sabine (smacking him): "Chop, wake up!" In A New Hope, C-3PO pushes R2-D2 and tells him, "Wake up. Wake up!" after the Jawas' sandcrawler stops [15:53], and in The Empire Strikes Back, Han similarly hits a control panel on the Millennium Falcon to get it working again [35:07].
35:05 - Ezra (after Thrawn says, "Whatever happens next happens to both of us"): "That's the idea." According to the subtitles, Greedo also says this in A New Hope; after Han says, "Over my dead body," Greedo replies in Huttese, "That's the idea" [50:44].
36:42 - Ezra (to the rest of the Rebels): "And remember: The Force will be with you always." Through the Force, Obi-Wan says the same thing to Luke near the end of A New Hope: "Remember: the Force will be with you always" [1:57:24].
