Dougie has produced some of the funniest scenes in all of Twin Peaks, but it's frustrating how people around him simultaneously act like it's totally normal but also uncharacteristic.
Like, based on Dougie's job and relationships and place in life, it's obvious that he had to have been a relatively normal, functioning dude. So it doesn't make sense for people to just shrug it off.
On the other hand, Jane Eyre made a comment about him having another one of his episodes. If that was the case, then why was everyone acting confused by Dougie's behavior?
