Improv Creepio

Not sure if there's someone we're supposed to report this to but I swear to God, there's one person I've noticed over the weeks at improv class who starts 99.99% of their scenes in a dark manner.  A really dark manner.  One scene I had started out in a graveyard.  Another started with the hammering of a stake into a vampire's heart.  My coworker and I have noticed this trend over a few weeks and aren't really sure what to make of it.  Either way, I'll refer to them from now on as Creepio.
