Jack watches the cruiser fade away and lets out a long breath. He hadn't been looking forward to finding out what might happen if he actually had to fight John's nightmare. He'd have done it--probably would have enjoyed showing just how weak and pathetic men like that were, not to mention showing off just how great he looked at all angles in these pants--but he knows that still could have made things worse. Given the way John had tried to stop him right away, he'd have put even odds on that nasty piece of the past actually trying to put him in cuffs, and there was no way that would have done anything good for John's mind regardless of the fact Jack would have…well, been himself about it; he isn't sure the guy's ready for his jokes about safewords.

Looking around at their surroundings or lack thereof, Jack leans in a little, forehead not quite touching John's, and drops his voice to just above a whisper.

"Do you need me to leave?" Because there's no way in hell he's just heading off after that without being given an explicit command, but he knows too well that sometimes it's too much to have other people there while you have to deal with the fallout of explosions in your own mind.
