Okay. So I came across the episode description from this episode and I could NOT wait for this thread to pop up. So I had to get it started on my own.
Episode 5.09 "Rachel Ben Natan"
Dawn Budge (Rosie O'Donnell), now a "Hearts 'n' Scalpels" producer, objects when the show is invited to participate in a gay-pride parade. Meanwhile, Christian falls back into old habits; Sean, on the outs with Christian over Julia, hires Gina (Jessalyn Gilsig) as a receptionist to get back at him; and Rachel Ben Natan (Maggie Siff), Matt's disfigured rehabilitation counselor, sees Sean when she experiences pain in her face, but her case proves to be more complicated than that.
HOLY CRAP! Gina is coming BACK to spite Christian! This is gonna be amazing.
