While Victor is no goddamn astronaut, he is a thief, and darkness is his good pal. He's not super well-versed in this tech so he may take a backseat on that.

Sully's not out for blood here, as far as he's concerned this thing should go down without a hitch. Which shows a curious lack of self-awareness on his part. So he's going to be fairly non-violent (and hell, he just turned off the lights, calm down pal), but if you point a gun at him expect the same in return. If it seems like a no-win situation he knows how to fold. He hasn't made it this far in life without having a self-preservation instinct.
