DOOL: When Tamara Braun played Ava Vitalli, who was it that she went psycho on?

Ava was a real nut job. She was Patch's girlfriend when he had lost his memory and Kayla was searching for him and found them in a seedy club. We didn't know for a while that Ava was actually very wealthy and was hiding from her father who finally got his goons to bring her back home and attempted to hold her prisoner in the mansion unless she was escorted with them. Kayla finally got to Patch and fought to make him remember their lives together and it was very drawn out but his memories finally returned while she was near death and isolated in the hospital. Bo and Hope wrote cheat notes for his regarding their lives so he could convince her that he was remembering and would fight to live. After she was through with Patch she went after John Black while he had lost his memory and Marlana was trying to help him. I really disliked Ava and her evil soul, not looking forward to her returning.
