Last night's Grey's Anatomy is not likely to be very well received by its fans.
Four new Mercy West doctors arrived at Seattle Grace, as the merger took effect. All our Seattle Grace favorites got their respective asses kicked, and one of them got fired.
That would be Izzie Stevens, who abruptly left after almost killing a kidney transplant patient (who ended up going with Miranda Bailey to L.A. and Private Practice at 10).
How long will Izzie be gone? Did she leave Alex? We can only wait and see.
Meanwhile, Lexie, Alex and Cristina fought to upstage their counterparts, while Callie's dad returned to convert her, but thanks to Arizona, he's the one who saw the light.
For the full rundown of events last night, here's our recap of "Invasion."
Izzie did not handle herself well amid pressure from Mercy West invaders.
