Halt & Catch Fire
Sam and Dean investigate a case in Spencer, Iowa where a truck mysteriously drove itself off a bridge, killing its driver, Billy. Believing it to be the ghost of Billy’s dead brother, Sam and Dean salt and burn the truck, but soon afterwards, a girl named Julie is strangled by her own computer cord after getting threatening messages on the Internet. Following the clues in the message leads them to a man named Andrew Silver who died in a car accident, but they are unable to put him to rest as he was cremated and doesn’t seem to be attached to anything. After a boy named Kyle is killed, they confront his friend Delilah who reveals that the four were involved in the accident where they caused the crash and didn’t try to save Andrew after his car was set on fire by electrical wires. Sam and Dean realize that Andrew is after revenge and is in the Internet, having used the power wires to access a nearby Wi-Fi tower when he was killed. Dean protects Delilah from Andrew while Sam talks to his wife, Corey, who admits she knew he was there and didn’t want to let him go. When Dean is unable to stop Andrew or convince him to move on, Corey speaks to him through FaceTime and convinces Andrew to let go of his revenge and be at peace. Afterwards, Delilah visits Corey to tell her what really happened to her husband. Meanwhile, Dean decides that while he won’t give up fighting the Mark of Cain, but he won’t continue looking for a cure.
