Hahn admits that she finds fellow attending surgeon Mark Sloan (Eric Dane) attractive but would rather keep her personal and professional lives separate to avoid attracting his romantic attention. Additionally, she befriends Callie Torres (Sara Ramirez), but their friendship weakens when Callie starts to suspect that Hahn is in love with her. At first, Hahn dismisses the idea with a joke, but then she surprises Callie by kissing her in front of Sloan to demonstrate that he couldn't manage a threesome with them. Callie gives Hahn another kiss in the Season 4 finale, and Hahn reciprocates.


In Season Five, the two struggle with their distinct approaches to the relationship as Erica Hahn and Callie Torres's relationship develops.

When Callie, uncertain of her sentiments, sleeps with Mark to examine her physical attraction to women and her capacity to relate to Hahn, this tension reaches its climax. Hahn is determined to keep the relationship alive despite these difficulties.
