Sara Ramirez, Grey's Anatomy Ramirez has struggled to find her place within the talented Grey's ensemble. It took two relationships — her character's aborted marriage to George and her nascent pairing with Arizona — for her to find it. This Tony winner has dealt with the utter shock of George's death and the profound sadness of her Catholic father's disapproval of her bisexuality with careful modulation (this isn't the stage, after all). Her portrayal has made her everyone's new/old favorite character.
