Teen Wolf, Season 5

[Stiles and Scott are sitting on the hood of the Jeep at Look-Out Point as they look up at the full moon overhead]

Stiles:
You alright? You starting to feel it?

Scott:
No. Just thinking...

Stiles:
About what?

Scott:
Senior year.

Stiles:
[scoffs] Senior year? Come on, that's-that's nothing. That's going to be easy.

Scott:
It's more like something Deaton told me once. You ever hear of "regression to the mean?"

Stiles:
No, I don't think so...

Scott:
It was his way of saying that life can't ever be all good or all bad. You know, eventually things have to come back to the middle. So, think about the last few months. Things have been good, right? But not amazing.

Stiles:
Yeah, but no one's tried to kill us in six months, either...

Scott:
Right. We've been pretty much in the middle for awhile. Which means... at some point, the scale has to tip one way or the other. Things are going to get really good again...

Stiles:
...Or really bad.
