Taylor is the other Haley sister.She slept with Nathan.
She was in season 2.
She didn't behave quite good to Haley,but she made her a favor,sending e-mails to Chris from Haley in order to send him away.
She didn't come back since then.
In season 7 she is the sister of Haley and Quinn.
She can be quite bitchy and slutty sometimes,but when she gets upset,it touches your 心 :).
In season 7 she returns with David-Quinn's former husband .
Also in season 7 her hair colour has gotten darker than season 2.
When her mother ,Lydia died ,she sat and cried :))
This was a very emotional scene ;]
