Mick Wolf was in Rolling Stone during the height of his rock career and he was a Cult favourite and the reluctant consciousness of rock Mick. He carried sober chip round with him in that was Ellie Harps during her pregnancy.
Mick Wolf portrayed to himself as a "visting musician" in Tree Hill, and came to Peyton's recording studio. Time passed, and Mick admitted to finally being the biological father to Peyton. In the episodes, Mick Wolf appeared as a recovering alcoholic, and when Peyton saw him drunk on the pool table, she took the chip away; however, discovered that it was her mother's before she was pregnant with Peyton. It was his reminder of Ellie, and of the sacrifice she made for Peyton.
After Mick had admitted to being Peyton's father, he left her behind once more, to continue along with his life, and enabling her to carry on with her own.
