Grey's 2.0 just got a major infusion of girl power. Sources confirm that Alias' Merrin Dungey and Judging Amy's Amy Brenneman have joined the cast of the Grey's Anatomy spin-off, er, I mean "the enhanced two-hour Grey's Anatomy episode with a potential for afterlife." Based on recent intel, my guess is Dungey will be playing a psychiatrist, and Brenneman a fertility specialist. But it could be the other way around. The duo's hiring puts to rest speculation (or concern?) that Kate Walsh would find herself surrounded by a mostly-male ensemble — buzz that only intensified with the recent casting of Tim Daly, Taye Diggs, Paul Adelstein and Chris Lowell. Pretty ftaktastic cast, if you ask me. This thing is really gonna have to suck to fail. You agree?
