I haven't moved him into the area, since the only completed M-U already has a rescue squad, but Sangamon Taylor is eventually meeting the generic bulletin-organized rescue squad up there. That is not the point of this post. The point is that he's going to try to hang around and
look into any open rooms after rescue squads start escorting patients back down
for any evidence left behind. If there is anything he should find, even if it's just a sterile syringe wrapper, please let me know? Or if you want the door to lock in his face, that's cool too. I don't actually expect him to learn much of anything -- he's just in the small stack of characters itching to put their investigative skillz into play.
He will be happy to share anything he learns with just about anyone, too. Which may or may not please your characters, but them's the breaks. Information just wants to be ~FREE~.
PMs/Email are fine since you may not want to let anything be public. Or if it's unclear what their own rescue squads will find and take themselves.
