2:13 - Kanan (to Hera, about the purgill): "Don't shoot!" C-3PO also says this to Jawas in A New Hope: "Don't shoot! Don't shoot!" [16:27].
15:42 - Zeb: "Refuel commencing." Han says nearly the same thing in Return of the Jedi, about the clearance codes for the stolen Imperial shuttle: "Transmission commencing" [54:55].
18:11 - Hera (as the purgill come to the rescue): "I don't believe it." Luke also says, "I don't, I don't believe it" in The Empire Strikes Back, after Yoda uses the Force to get his X-wing out of the swamp [1:13:10].
20:51 - Hera: "I have to admit: without the help of the purgill, we never would have gotten off the ground again." Obi-Wan makes a similar comment near the end of Attack of the Clones: "I have to admit that without the clones, it would not have been a victory" [2:13:26].
