[Dipper was right on the money there. When he came back he'd lost all of these memories- and then Oscar had given up his leg to get them back. It adds another layer of guilt to the whole process. Oscar knows, now, what memories he gave his leg up for and doesn't regret it. But that doesn't mean Dipper will feel the same way.

He smiles, but it's wry, pained.]

Not for want of trying, anyway.

[The...killing thing, not the...Bill Cipher thing. Obviously. Probably. ]

I know. And I have been keeping it. But...this place? Well- Deerington, anyway, it had a way of dragging secrets out in the light if you want it or not. I... I'm trying to be better about that. Let the people I trust with it know the truth.

[So they don't have to learn in the worst possible way. He exhales softly.]

Okay. So, because this is you and I know you'll want to know the details. There's two magical forces in my world- they came from the sky- the sundrop and the moonstone. They were meant to be together, but they split apart and landed in different parts of the world. The sundrop landed in a flower- and that flower was used on the queen when she was in labour with the princess of our kingdom. It gave her magical hair. The moonstone landed in a different kingdom- and it created sharp, indestructible rocks.

...I know all of that sounds crazy and I really can't explain the whys or hows. My world is really magical, and those are the two biggest pieces of magic there are. They just... are a thing- but important for this...whole story. Background.

[With most people he glosses over this, but Dipper is like him. Dipper picks and prods at the tiny details, tries to understand them better.]
