Carina

From Chuck Wiki

Carina is an undercover D.E.A. agent who appeared in "Chuck vs. the Wookiee". She loves taking risks and is not very trustworthy. She seems to have a past with Both Casey and Sarah. with one being one of professional respect and the other of professional disdain.

To keep Chuck's cover, she went on a date with Morgan (who she called "Martin"). Carina was convinced by Chuck to save Sarah.
