Thought it was a great episode. Fitting end.

Thinking Patty got pushed off a roof when she simply passed out.
Ellen being able to break away from that path after becoming Patty.
Great shot at the end. Patty heartbroken that Ellen was able to break away. She's successful as shyt, but has nobody to share it with. Even her protege was able to see that the path was wrong and is happy now.
Great to see them tie Michael being at the apartment in Season 1 to this. Michael dying because of Patty was great although Scully killing him didn't make any sense.
