The gang is back for class after the summer off. Greendale will always be Greendale no matter how normal Jeff may wish it (through song) to be. Abed discovers British TV - including Cougarton Abbey. Jeff learns about himself, we meet some new characters, and some old ones go on new journeys.
The forementioned Cougarton Abbey.
Pearch and Jeff dynamic.
Jeff post Chimpanzzzzzz.
OMG the Vice-Dean!
No John Oliver.
I love Community - you all know that. This was a great entre back into the show. It wasn’t a big set piece like some previous episodes, but it nicely set the scene for the year to come, while getting us up to speed on the Summer and the new characters (or changes in direction for existing ones).
