In the past week or so, Isaiah's definitely been building credit for a ticket on the perceived-as-crazy train, blaming racism for the discomfort his booming words caused on the show, blaming TR for the campaign that ultimately got him fired from the show, and now, in a prime time interview with Larry King-- blaming costar Patrick McDreamy Dempsey for the fight that started-- and ended-- it all.

Isaiah told Larry that he and Patrick never got along and that Patrick was constantly showing up late on the set. The fight though, was sparked when Patrick insisted on waiting for his costar Ellen Pompeo, before they began shooting for the day.
