Tim is well aware that he's let his discomfort be readily apparent, but he doesn't really care. He's exhausted, too distraught by the place in general, to be worried about how he's coming off to some random person that he just had to sit and confess some sanctimonious truth to.

He considered the door, the man, that smile. No, Tim didn't want his back on this whole situation at all, and not least of all because he thought turning his back on the room might reset the whole situation somehow.

Maybe thinking about it too much was a surefire way to manifest something. Probably better to just rip the band-aid off and get it over with. He stepped out of the door, holding his breath like that made a difference, and when he was through he turned back around so his back was only to the room and Kisame for a moment.
