In I Went to the Woods, Marty gets into a drunk car accident and he dies, but Stefan possesses his body and starts trying to save some of the people from the bus Marty hit. After almost getting arrested and handcuffed, Stefan escapes and gets his cuffs off at an unknown cabin. It's revealed that Marty has previous history of alcoholism and would die in the cold from detox. Stefan is then found in the cold by Damon and he gives him some food to eat. It is then revealed that Marty's body is beginning to die since a human body can't hold a vampire soul.
