Even when Mark is dating Lexie, Mark and Callie remain close friends. He even sticks with her when she decides to become bisexual, comparing her sex with Mark to the sex she had with Arizona Robbins. Mark and Lexie break up and Callie begins to date Arizona, but their friendship never fails. It isn't until Arizona leaves for Africa and breaks up with Callie that Mark and Callie have sex again. Not long after, Arizona shows up at Callie's front door, saying she was wrong. The two of them ultimately get back together, but Callie finds out she is pregnant with Mark's baby.
