A guard hears Tracy attacking the other guard and tries to use his walkie talkie. He realizes something is wrong so he gets his cattle prod out. He turns around to see Josh standing there and attempts to hit him but Josh absorbs the electricity whilst killing the guard. Once the pack are inside Lydia's room he says "She doesn't look good" whilst looking down at her. Josh and Theo are outside Sinema. Josh explains that he took a lot of drugs but they weren't working. Theo says that he heals too fast and Josh says he should have left him for dead. Theo gives him a pair of jumper cables to hold on to. He attaches them to the battery and Josh roars as electricity sparks around his hands. His eyes glow purple. Later, Josh and Tracy attack Scott but Josh ends up paralyzed because Scott grabs Tracy's wrist and her claws go into his chest, killing him. He is then carried out by Corey and Tracy.
