Alvin looked around the room, trying to take in everything that was here...and then the door locked.  He immediately turned around and started pulling on the door.  "Damn.  Well, no going back out for the time being."  He carefully approached the flower vases, looking at them.  "Hm.  Wonder if it's some sort of puzzle..."  Alvin looked over to the door.  "Hey, check this out...it's blood.  Wonder if it's human or something."  He checked around the room...was this a trap?
