Greggory overheard a hint of something, 'Someone else coming back?  And someone HE wasn't expecting?  That's not good.'  He quickly marched over to the door, and turned before he left, giving a sympathetic smile to the nurse, before heading out.  "About time I get to a security station and find out what's going on.  Wouldn't surprise me if someone's just not reporting in on time, probably enjoying one of the subjects or something." *sigh*
