[There's a moment of brief annoyance, but he can't really be surprised he's not getting off with a half explanation. So instead, he'll give the kid the full explanation.]

Alright, you want the full story?

The day my best friend moved to town, he met a goddess in disguise at a gas station who gave him the ability to enter TV's. We got interested because of a supernatural TV show connected to that world that only airs at midnight on rainy nights. He was showing us how he could enter the TV when we all fell in.

Then when people started dying, I convinced him to go in with me and investigate. My shadow showed up, I denied it, it tried to kill us, he beat it up, I accepted it and that gained me the power to go into TV's too.

That clear it up?
