Miniver
You don't have to be happy, but um... I suppose for what it's worth, I'm not like mom and dad. I'm especially not like Kathleen. She may have squatted me out and dumped me on dad before taking off, but I'm nothing like her.
... Look, I know this is hard to believe, Miniver, but a little over a year ago, an older you welcomed me here and took me in when my wife was still in our own world. You gave me an older brother I always wished I'd had, and right now I'm really trying to keep my cool because I know that if you're as young as you look, you're probably not going to accept me. You certainly won't accept Keller, either, because he's a downright prick, but please. Don't ever disappear on me, okay?
