Twin Peaks original series (ABC)

‘How’s Annie?’
‘Beyond Life and Death, Episode 222

After escaping from the Black Lodge, something just seems off with Cooper — and then he goes into bathroom to brush his teeth, squirting a tube of toothpaste into the sink in anger before bashing his head on the mirror and repeatedly asking, “How’s Annie? How’s Annie?” in a super-creepy way. His reflection is of BOB and that’s the way the original series ends. We are dying to find out what happened next.
