Question: You mentioned a while back that George's mom was returning to Grey's Anatomy. Did the strike push that back?
Answer: That's what I'm hearing. According to my Seattle Grace mole, Mama O'Malley's return originally slated for November sweeps was delayed until Episode 11, aka the show's final pre-strike episode. That probably explains why George had little to do during the just-wrapped two-parter. Why'd they move her out of sweeps? Well, per my spy, when it became clear that eppy 11 might be the final hour of Grey's we get in a long time, the script underwent "massive rewrites" to ramp up the drama and add several cliff-hangers one of which involves George's old lady. "They're pretty big bombshells," says the source. "Basically, everyone's futures are left up in the air." Well, not everyone's. As I reported in this week's Ausiello Report vodcast, by the end of the episode there will be little doubt which direction the Mer/Derek/Rose triangle is headed in.
