On the season finale of Community...

- Troy solves the murder of Vice Dean Laybourne and decrees that air conditioning school must act like a real school. He can do that because he's their Messiah.

- Abed went Evil Abed for a bit, in response to Troy being away, but Jeff made a passionate speech about friendship at a trial to decide whose name should go on Shirley's Sandwich Shop and it turned Abed back to normal, while inspiring everyone to be better people.

- Jeff also ended the episode looking up his father online.
