7:44 - Kanan (to Maul): "You're not walking off this rock in one piece." Luke uses a similar expression in A New Hope; after C-3PO asks if there's anything he can do to help, he replies, "Not unless you can alter time, speed up the harvest, or teleport me off this rock" [19:58].
7:49 - Maul (to Kanan and Ezra): "I have planted a beacon nearby. Strike me down, and it will activate, revealing your presence to the Empire."

8:30 - Kanan (after Ezra agrees to go with Maul): "I do not like this." This is also Leia's reaction after the Millennium Falcon lands in Cloud City in The Empire Strikes Back: "I don't like this" [1:19:58].
10:46 - Maul: "Trust me, Ezra." Han also says, "Trust me" (to Leia) in The Empire Strikes Back [1:20:06].

17:36 - Sabine (possessed by a Nightsister, to Ezra): "You're unwise to re-enter our sanctum." Vader makes a similar comment to Luke during their duel in Return of the Jedi: "You are unwise to lower your defenses" [1:49:24].
