I’m just along for the ride. I just assume the writer’s wanted to head in a new direction in order for the teens to have some more angst in their teenybopper lives, (like Mia didn’t have enough already).
I’m not blaming Mia – her entire life has been a mess. Mia seemed fairly sweet and innocent when she first came on board. However, this complete turn-around in personality just doesn’t happen to people, even with Nicole doing what she did to her and Chad wasn’t all that helpful (even though he didn’t know about the baby).
I would think that she’d unleash all that anger (deservedly so) on Nicole (when she returns) and if she wants Chad go get him (you’re right, she doesn’t know what she wants) – but given her crazy mixed up life so far – she may have that problem forever. I also hope that "new" Will, will help her sort out just exactly who and what she wants.
