Jack was going to be polite about it as he stays where his body lies with his face flat on the TARDIS floor. Of all wounds it was getting shot in the head that was a pain in the arse especially seeing Jack had to regain all sense of judgment in the process. This wasn't exactly smart either.

Eventually, the wound that was there is gone, bone, skin and hair are all back where they should be. There's some movement in Jack's hand and eventually, his lungs fill up with air as he gasps for that breath. Nice way to freak someone out, Harkness but it seemed to be an easy way to give some proof to the other.

Jack slowly pushes himself up from his position on the ground never mind the bit of gore he's got on himself. "Here I am in a room with another gorgeous man. Wow. I don't get a come back like that so often. Wait. No. I do." He laughs and he turns himself around on his backside.
