4:54 - Hondo (to Ezra): "Well, hello there!" "Hello, there" is also Obi-Wan's greeting to General Grievous in Revenge of the Sith [57:30] and to R2-D2 in A New Hope [30:07].
6:31 - An Imperial light cruiser passes overhead, similar to the Star Destroyer at the beginning of A New Hope:
12:21 - Azmorigan: "Die, you pirate scum!" C-3PO (with his head on the body of a battle droid) has a similar line in Attack of the Clones: "Die, Jedi dogs!" [1:53:27]. Insults involving scum also appear in Revenge of the Sith (General Grievous calls Anakin "Jedi scum" [19:12]), The Empire Strikes Back (Admiral Piett remarks, "Bounty hunters!? We don't need their scum." [1:05:52]), and Return of the Jedi (an Imperial officer says, "You rebel scum" [1:33:51]).
12:28 - Hondo (to Ezra): "What's the plan?" In A New Hope, Han asks Luke almost the same thing: "What's your plan?" [1:11:56]
