Andrea is one of the Atlanta camp survivors and is the older sister of Amy. The two sisters were on a road trip, with Andrea taking Amy back to college for the fall term, when the Wildfire outbreak occurred. After experiencing car trouble, they were picked up by Dale Hovarth in his RV and the three ultimately ended up on the outskirts of Atlanta.
Prior to the end of the world, Andrea worked as a law clerk. She ultimately decides – after losing Amy in walker attack at the camp – that she will not be a victim anymore and her natural talent as a sharpshooter emerges when the group is trained in the use of firearms. Unfortunately, the first time she attempts to take out a walker, it is a battered and bloody Daryl that she shoots instead. Fortunately, she only grazes him.
Andrea is played by actress Laurie Holden, who was born in the U.S, but now holds dual American/Canadian citizenship. She is best known for her role as Agent Olivia Murray on the television series The Shield, along with a recurring role on The X Files. She has also appeared in the films The Majestic, Fantastic Four, and Silent Hill and the made for TV movie The Mist.
- Laurie is her middle name; her given first name is Heather.
- Holden made her acting debut at the age of 6 in an episode of The Martian Chronicles. Her step-father, Michael Anderson, directed the television series. One day while Holden was visiting the set, a young actress cast to be on the show failed to show up for work. She soon found herself on camera, replacing the no-show youngster.
- Frank Darabont, who developed TWD series for television, first noticed Holden when she appeared on stage in Cat on a Hot Tin Roof.
- In the graphic novels, Andrea and Dale become involved in a romantic relationship, despite their age difference.
- In the TV series, Andrea becomes involved with Shane; the two at least share a “quickie” sexual encounter in the car after returning from one of the many search missions to look for Sophia and kill multiple walkers.
- No last name is given for Andrea in either the graphic novel or the television series.
