Preempting an order is still satisfying for Bruce, because it's done to spite him - or maybe he just likes the glare.

That said, he was going to leave the shirt out of the equation. Oh well, he'll 'let' that one slide.

He leaves Zerxus there (with a pat on the head) to go pull a pair of pajama pants on. It's the exact same pair, and he does leave his shirt off.

"Good. Now shift over." Not an order again, this time.
