Michael Ausiello reported today that T.R. Knight is asking to be let out of his contract with Grey's Anatomy. Rumors suggest that he has been unhappy on the show, perhaps going back as far as "Isaiahgate," when former co-star Isaiah Washington referred to the out actor by using the f-word. Ausiello's contact, however, says this is not the case, and that T.R. just feels "it's time to move on."
