Teddy Altman - "Grey"s Anatomy" Character Teddy Altman
Teddy Altman, played by Kim Raver, caused a lot of tension between Owen and Cristina. She first came when Owen asked her to because Cristina really needed a good cardiothoracic surgeon to mentor her. The tension began when Cristina discovered that Teddy had feelings for Owen. Owen wasn't sure of his feelings toward Teddy, but ultimately chose to be with Cristina.
Heartbroken, Teddy tried to leave, but was unable to for business reasons.
Teddy began a relationship with Mark Sloan, but that fell apart when she found him in bed with Reed.
