While John's been keeping very low for the most part, he's also spent a good amount of time and will continue spending a good amount of time watching people to see if they zone out. There could be enough skulking to seem suspicious? If they're enough on edge to stretch it that far, I'd be willing to go along with it.

OH ALSO he... might try to investigate the whole explosion thing himself? Once work at the hospital calms down. I don't know. But that would probably be... really suspicious. So I could maybe get back to you on that?
