You'd better do something quickly, before the guard has a chance to pull out a gun or call for backup, so you spin around, mutter, "sorry," to Bruce, and - before he has a chance to process what's going on - punch him. You're not gentle about it, either.
It does what it's supposed to do. Bruce stares at you, shocked, for about a half-second, but he's already transforming, and in no time flat the Hulk has smashed his way through the locked doors and the three of you have easy access to the prison blocks.
Sitwell opens his mouth as if he thinks protesting will still help at this juncture, but closes it again, grabs you by the sleeve of your jumpsuit (the Hulk's is history by now) and runs as the alarms begin to go off all around you.
You think about apologizing to Sitwell as well, but don't.
