Well, let's just say she can use a little more loving care with her students, particularly Cristina.
[...] I felt sorry for Hahn because Hahn grew up in a surgical world that included even fewer women than there is now (so Hahn is accustomed to a "dog eat dog" kind of surgical world)." Trish Doolan, who consulted with the show's producers on the developing lesbian storyline between Hahn and Callie Torres, said of the character: "She's very strong, very good at what she does, and actually a lot of men are threatened by that.
Hahn reappears in season three when she is contacted by George O'Malley (T. Knight) for a consult on his father's valve replacement after George finds out about Burke's hand tremors and Cristina helping him cover it up.
Hahn transfers to Seattle Grace Hospital in the season four episode, "Haunt You Everyday", after performing a successful heart transplant at the request of the Chief of Surgery, Richard Webber.
Clearly it's not an issue as we have a lesbian character on the show – Calliope Torres.
Sara Ramirez is an incredible comedic and dramatic actress and we wanted to be able to play up her magic.
I believe it belittles the relationship to simply replace Erica with 'another lesbian.' If you'll remember, Cristina mourned the loss of Burke for a full season.
I was very excited when they told me that Erica and Callie were going to have this relationship.
The storyline was praised for its realistic portrayal of a developing same-sex relationship between two women, although consultants from the Gay & Lesbian Alliance Against Defamation expressed some concerns over what they deemed the somewhat exploitative talk of a threesome between Hahn, Torres and Mark Sloan.
Hahn was written out of Grey's Anatomy in November 2008, with Smith commenting that the decision originated with the ABC network rather than with series creator Shonda Rhimes.
She later confesses to Addison Montgomery (Kate Walsh) that she is purposely hard on Cristina, as she reminds her of herself as a Resident.
The character deflects the romantic attention of fellow attending Mark Sloan, admitting that she finds him attractive but wishes to keep her private life separate from her working life.
Unfortunately, we did not find that the magic and chemistry with Brooke's character would sustain in the long run.
