|Oh yeah I know, it just seemed like such a specific line, esp. when she said "Stuff you dont even know!" because he knew about all that stuff pretty much. I guess you can just assume/fanwank that she was talking about all the Peyton drama, but yeah|
Nah I wouldn't say Peyton knew how Brooke felt about graduating high school and feeling like she's the only one who doesn't have a passion/path. Or how she felt about missing Luke when he went to look at colleges with Karen and not sure if he missed her back etc.
But yes, mark didn't think of any of this whn he wrote that line; just that it was a seed planted in case he made Brooke preggorz (which I wish would've happened!)
