One Tree Hill, Season 6

Brooke:
You must be Julian.

Julian:
Brooke Davis, I've read all about you.

Brooke:
Good. Then you know being the third person in a Lucas/Peyton love triangle usually doesn't end well.

Julian:
For who?

Brooke:
I think it's pretty clear in the book if you're not Lucas or Peyton you should just forget it. And just so you know, they are two of my best friends. So if you mess with them, I will mess with you.

Julian:
That sounds like fun.
