Bill Forbes

William "Bill" Forbes is the father of Caroline Forbes and the ex-husband of Elizabeth "Liz" Forbes. The marriage between Liz and Bill apparently turned sour after the revelation that he was gay. He is believed to have left Mystic Falls after their divorce but always maintained a close relationship with Caroline who, in a fit of anger, told Liz that if she wanted advice about boys, she would go to her father.

In the beginning of season 3, he gets a call from Carole Lockwood who told him that his daughter was a vampire. He made his way to Mystic Falls and was responsible for torturing his daughter using the old Lockwood jail celler where there was vervain in the ventilation system and a secret lever to open the window to the sun. He continued this for at least a few days before Liz rescued her aughter with the help of Tyler Lockwood.

After the initial shock of seeing his daughter the way she was, Bill appears to have calmed down and calmly tells her that he doesn't think she'll ever be okay again. He leaves once again.
