Rose

Rose is a nurse at the SGH.

Personal life
Despite being Derek Shepherd's ex-girlfriend, Meredith and her got on well, although she was intimidated by her legendary relationship with him. Addison disliked her and Mark disliked her too.

Romantic life
A year before she met Derek, she was engaged, but she called it off because they both wanted different things. The diamond was her grandmother's so she wore the ring around her neck on a necklace.

Rose started dating Derek after they became friends. They kissed and soon started dating. Despite their seemingly happy relationship, Rose was slightly bothered by comments made by hospital personnel about Meredith and Derek's breakup only being temporary and her being the McRebound (the rebound girl). Mark commented that she was stringing sex along like a prize but really she was afraid that once she gave it up, he would lose interest. She and Derek had sex but the whole time he was thinking of Meredith and forgot to call her afterwards.

He and Rose continued dating but after saving their first clinical trial patient, he and Meredith kissed and she asked to get back together with him. He said he would and left to break up with Rose. Although she initially took it well, she then decided she hated Derek and became very unpleasant towards him. She pretended she was pregnant and she carelessly handed him instruments in surgery, accidentally cutting him. She realized she was only damaging her reputation and left for an opening in pediatrics.

Career
She works often with Dr. . She has been the attending nurse for over 30 of Derek Shepherd's surgeries, as Rose stated in Forever Young. She still held feelings of resentment towards Derek after their break up and after carelessly handing Derek a scalpel in surgery, she accidentally cut his hand causing it to bleed. After realizing that she was no longer the scrub nurse everyone wanted, she quit as a scrub nurse to take up a job in peds.
