Eric Dane a.k.a. Dr. Mark “McSteamy” Sloan, who made his first appearance on Grey’s Anatomy last season and closed this past Thursday’s episode by walking out of a hotel bathroom wearing only a towel, is joining the cast full-time, ABC says. His appearance Thursday closed a scene in which Dr. Derek “McDreamy” Shepherd (Patrick Dempsey) was breaking up (for good, apparently) with his estranged wife, Addison (Kate Walsh).
Sloan was the reason Derek moved to Seattle in the first place, when his former best friend slept with his wife. His ongoing presence will either set up two interlocking love triangles (Meredith-Finn-Derek and Derek-Addison-Sloan) or one big love pentagon. Or, if the Shepherds’ marriage really is done for good, at least give Addison a new man.
Dane played “Multiple Man” (Jamie Madrox) in the summer flick X-Men: The Last Stand and also has a part in the Project Greenlight movie Feast.
His TV credits include another ABC medical drama, Gideon’s Crossing, a recurring part on Charmed and the 2004 CBS movie Helter Skelter. He’s also guest-starred on Las Vegas and Roseanne.
