I guess the trooper didn’t have too much of an issue with Moloch bringing the hounds in then. Having them shown in the movie feels a bit odd. Only thing I can think of is that it’s a delaying tactic of some kind to make Han’s escape possible. As if the successful bridge run wasn’t odd enough.

Distinctive verbal phrases are good to have for NPCs. It helps keep track of who’s talking, brings a bit of color/life to the character, and makes them more memorable. Not necessarily more memorable for their name, but I’m gonna remember the minion that clarifies their word choices a lot more than the one who hasn’t.
