In the infamous words of Law & Order's Serena Southerlyn, "Is this because I'm a lesbian?" Dr. Erica Hahn is getting summarily discharged from Seattle Grace only a week after she came out of the closet and saw the leaves through the trees or whatever. Rumors are that ABC didn't like her racy "south of the border" storyline with Callie. (Though Shonda Rimes insists in a statement that Smith wasn't fired because her character was a lesbian, and that they still have Callie, a lesbian, on the show). In her interview with EW's Ausiello, Brooke Smith says she was told they couldn't write for her character any more.
So last night's episode marked the final appearance of Brooke Smith, aka Seattle Grace's Dr. Hahn. There's still speculation on if it was because her character was gay, or if they just didn't know how to deal with giving this ballbusting surgeon a romantic relationship, or if they just wanted a hotter, younger model. But whatever it was, I personally thought that the exit was abysmally handled. They should take a page from the ER handbook of how to write out characters, because when someone leaves this show, it's like bang and they are gone.
