Anna was Chris Griffin's girlfriend in Long John Peter. She met Chris at the veterinarian's office when Brian had to go.
Anna, a self-proclaimed animal lover, worked as an intern there for Dr. Jewish. Anna and Chris went out and were boyfriend and girlfriend.
Peter advised Chris to be extremely rude and mean to Anna. Chris did and Anna dumped Chris at the movies.
At the end, Chris apologized to Anna and they became girlfriend and boyfriend again, and went out on a date to the movies.
However, Anna has not been seen since and in that time, Chris has been seen dating other women, so it can be assumed that the romance ended at some point.
Of note, she was depicted in promotional artwork as having brown hair rather than blonde.
She was voiced by Amanda Bynes and she was the love interest of Chris Griffin.
