Well, Haley really let me down in S2.
Don't get me wrong, because I think they're both to blame. But in a certain way, Haley was the one who started everything. I do agree the biggest issue was Chris and not music and what the show made us believe was that Chris kissed Haley, not the contrary. For some it might be the same, but for me, that makes a difference. I do believe she never developed feelings for Chris, she was just envious of what he had and his 'relationship' with music, because he had what she'd always dreamed off.
Basically, she was wrong for lying to Nathan about the kiss and he was wrong for making her the ultimatum. I do understand where they were both coming from so I can't put the blame just in one but the two of them.
And I love Nathan, don't get me wrong, he's my 2nd favourite, but I just think people paint him more innocent in S2 than he actually was. Just like I think Haley's seen as this devil bitch and that's not exactly true, either. They were both young, they both made mistakes, they were BOTH to blame. Not just Nathan. Not just Haley. Both.
