TJ's Inner Demon

TJ's Inner Demon is the antagonist of the episode I Promise.

Appearance
The inner demon appears to be a small baby with pale skin and a blond pouf of hair. He wears a white diaper with a heart shaped fastener, and carries a pink bow.

Personality
While he seems friendly at first, he becomes more and more sinister the more he talks, trying to convince TJ to do immoral things.

Summary
TJ's inner demon appears on his shoulder after he realizes that he has a crush on Shelley. First he recites everything TJ likes about her, and then starts to give some questionable pieces of advice.

After TJ has a talk with his dad about the difference between married and unmarried couples, the inner demon tries to pressure TJ by showing him people behaving promiscuously on TV. This results in TJ getting rid of his TV completely.

The next day, the inner demon is once again taunting TJ, but becomes excited once he learns that TJ is going to confess his feelings for Shelley. TJ presents Shelley with a promise ring and asks her to be abstinent with him, and she agrees; the inner demon dissolves into dust.
