According to this sneak peek from tomorrow night's episode of Grey's Anatomy, it's bring your girlfriend to work day at Grey Sloan Memorial Hospital, and it's as awkward as it sounds.

"Map of You" finds Owen inviting his new girlfriend Emma Marling (Marguerite Moreau), an attending at Seattle Presbyterian, to the hospital to observe a surgery. Is Cristina a fan?

Watch the scene below, in which Cristina and Owen chat about his new girlfriend hanging around the hospital, while the tension lingers between Cristina and Meredith as well ...

While she's also a doctor, Emma wants to make sure people don't think she's using their relationship to her advantage from a professional standpoint. Good luck with that.

Cristina seems surprisingly cool with it so far - or at least puts on a good front - although she is more distracted by best friend Mer, who is feeling "weird" around her "person."

With Oh set to exit the long-running ABC series at the end of Grey's Anatomy Season 10 fans can expect to see things get pretty complicated and emotional for Owenstina.

Cristina's made this decision that they should break up, which he's agreed to, but is he really ready to accept that and move on? It will be interesting to see in the coming weeks.
