Today we pair Salon‘s often contentious Editor-at-Large Joan Walsh, a frequent guest on MSNBC’s “Hardball” and “Grey’s Anatomy’s” Dr. Erica Hahn played by actress Brooke Smith. Hahn’s character was known to be a workaholic. She rejected romantic gestures from McSteamy (Eric Dane). She had a lesbian relationship with fellow physician Callie Torres played by actress Sara Ramirez. Smith was written out of the series in 2008.
