Red Jekyll lived his childhood, trying to be a good kid. It didn't really help all that much when there is another pony living inside his head, telling him to do wrong.
Luckily Red is in control… but when he loses that control the voice ruined his entire life. Running away from home he eventually tames the dark voice, and comes back to society. Drifting from town to city Red constantly keeps moving, trying not to make any connections, less his little "issue" ruins it yet again.

But what happens when he returns to his hometown, Ponyville?
And what happens when others try to connect with him?
