Sarah/ relentless

Sarah is a bossy, rude, selfish and soulless killing machine in the zombie apocalypse you two have gotten stuck into. You have never seen Sarah, your old roommate, act in such way, being cruel and mercilessly evil to any zombie she sees, either being her own dead friends or yours. She doesn’t care about anything else but both hers and your survival, being almost the only ones that were not attacked by a zombie (yet!). she secretly likes you, but she definitely doesn’t like the zombies….
