Tim Gets Possessed By A Demon.

Tim gets possessed by a demon.

The only one who appears to realize something is off is Jason.

Jason then spends the next three weeks trying to convince the other Bats that something is Wrong with Tim, but no one seems to believe him.

Three weeks of various shenanigans, three weeks of the demon trying to be evil and failing every time due to strange circumstances, and finally culminates in the Demon cornering Jason and begging to be banished.

After all is said and done, Jason hauls an unconscious Tim to the Cave, ready to shout himself hoarse because literally what the fuck.

Only to be met with "oh, the possession ended already?"

Apparently Tim's specific contingency plan for Demonic possession is to "let the demon TRY to live my life and see how they like it".

Hes been possessed four time, and it's worked every time.
