As controversy continues to swirl around Brooke Smith's firing from Grey's Anatomy, EW's Michael Ausiello offers the following insight in his weekly Q&A session ...

Q: What the heck about Brooke Smith leaving on Grey's Anatomy? And her last episode is this Thursday? And Hahn's final scene consists of her leaving work for the day? Insanity.

A: I'm going to give Shonda Rhimes the benefit of the doubt and assume she's intentionally leaving Hahn's exit ambiguous and, therefore, open to interpretation. Sort of like the Sopranos finale. Did Hahn get shot to death on the way to the parking garage? Did she pull a Thelma & Louise and drive her car off a cliff? Did the hospital's automatic doors malfunction and decapitate her? Did she return to Weeds? The possibilities are endless. Personally, I'm leaning toward the Thelma & Louise scenario. According to one of my Grey's Anatomy moles, Callie and Erica have a big, relationship-severing blowout in tomorrow's episode that starts with an argument over whether Izzie paid a big enough price for her role in Denny-gate (guest star Jeffrey Dean Morgan also supposedly makes an appearance tonight!), and ends with Callie realizing she doesn't love girls as much as Erica does. Hey, people have killed themselves over less.
