they both changed loads of course they're much better people now ... but nathan changed the most imo he was a mess back then and he's lovely now! he couldn't have done it without haley!
naley always and forever

i think lucas changed too. he was kinda a nerd and now hes amazing lol. not as much as nate tho

I THINK BOTH

they have both changed so much from the people they were in season 1 but Brooke has done some pretty great things that have made her just a little bit better. Angie comes to mind.

Brooke she has come along way from where she was in S1...though I have loved her since S1.

nathan changed a lot since s1 and he's got haley to thank for that..he's such a great guy now, almost perfect

lol Nathan has changed but not as much as Brooke. Nathan kind of went back and forth. Hence, point shaving, the guy he tried to hit after they won the champs, his leg injury and when he tried to hit Jason.

Brooke...

im choosing brooke because she still continues to grow and evolve through out the whoel series, nathan changed but he'd totally flipped by the end of season 1.
