The Doppelganger Incident in Night Vale

Dr. Lebel needed Dana's DNA to test against the cadaver and with a ban on science, she couldn't ask the sheriff for a sample. She sent Dr. Jones to secretly steal some of Dana's hair from a comb or saliva from a toothbrush and bring it back to the lab. When I burst in, he wasn't stealing anything, he was just using this time away from Dr. Lebel to figure out how to escape her maniacal grasp. He would ruin him, as she's ruined so many others who have left her service In the case, she's trying to ruin Carlos now, not merely by destroying him, but by destroying everything he loves Doctor Lup
