...because the election isn't the only source of intrigue around here. Entertainment Weekly reports that "Grey's Anatomy" has abruptly dropped Dr. Erica Hahn, the hard-edged surgeon played by Brooke Smith, who had recently gotten into a lesbian relationship with Dr. Callie Torres. Her last episode will air this Thursday, with no apparent closure. Michael Ausiello's sources tell him this was an order from ABC, not the brainchild of the "Grey's" producing staff. And notes that the relationship was taking an explicit turn. Conspiracy theories, anyone?
