Hey Daniel, have you been watching the latest Marvel movies and TV shows?

I hope you're not going to ask me about the physics of it.

Ooh, I was going to ask you about time travel in Loki.

No, my God, there are no branches to timelines.

Oh my gosh.

Or maybe I did go back in time,

and this is a better outcome than the one that I originally pitched to you.

This might be the best timeline where that could be.

Maybe you just don't know how much worth it can be.

If this is the best it gets, then it must get pretty bad.

Oh boy.
