Landel has consistently displayed nearly all of of the traits of a Mad Scientist, or at least a mastermind with an increasingly tenuous grip on his situation. He has been acting increasingly erratic over the past few nights, as various problems presented themselves (faulty wiring in the intercoms, apparently being overworked, et cetera). It's really only a matter of time before personalities of this kind self destruct.

Doyle would leave a few items hidden throughout the Institute, their locations usually given through needlessly cryptic hints. He appeared twice in person, once posing as one of the 'patients', once at night to directly take requests for items from individuals. Before any of the items could be given, he was killed. It seems he has come back.
