Brooke then Nathan! They've had the biggest transformations...Just like Karen said....

Peyton,Haley and Luke still have a bit if not more of themselves from when they were young,now(which is a very good thing)......

Peyton and Haley are tied for third and Luke is last...he's stayed true to himself(which is both a good and a bad thing)

i think nathan has changed the most and lucas the least

My two favorite characters. Brooke and Nathan! They have both changed for the better (IMO). Brooke has definately changed the most though.

nathan, then brooke definetly, then peyton and haley tied, lucas the least :)

Nathan and Brooke, both changed a LOT. =)

Brooke OR Nathan have deffinitely changed the most.

Defenitelly!He became just the oposite of himself!
Brooke too.

brooke and nathan!
no doubt about it

Definitely Nathan! He was a JERK in season 1. Atleast Brooke was still nice and stuff in season 1. Until Nathan met haley he was a jerk

and Nathan!!
They have both changed alot

I'd say Brooke, Nathan AND Deb! Brooke started off as the bitchy girl who didn't really care about anything, she let her guard down & became such an amazing person! Nathan also changed a looot because he fell in love withe Haley. Deb because she was the classy elegant lady & now shes the washed up ex pill addict cougar nanny

my boy (L)

and Brooke :)
