What's wrong with Wilford?

Something is going on with Wilford Warfstache. His episodes of insanity are happening more and more often, causing those around him to worry. Is this just part of the pink ego's usual insanity? or is there something greater going on?

This is a series, originally meant to be oneshots.
Wrote this a while back and posted to Ao3, but since I just wrote another part in the series I thought I would add it here as well
