Changes

[[Sam]] and [[Dean]] turn to [[Bobby]] for help. When [[Meg]] turns up, they capture her, and manage to find out John's location. The boys rescue John and take him to a remote cabin. It is while he is telling Dean he is proud of him that Dean gets suspicious and realizes that John is possessed by [[the Yellow-Eyed Demon]]. He taunts Dean and Sam and is killing Dean when John manages to wrest control for a moment and allow Sam to get control of the Colt. Sam, however, can't shoot to kill and the demon escapes after Sam only shoots John in the leg. As they escape in the [[Impala]], a demon-possessed [[Trucker|truck driver]] totals the car.

===[[2.01 In My Time of Dying]]===

All the Winchesters are in the hospital, with [[Dean]] near death. When [[Sam]] discovers John is planning on pursuing the [[Yellow-Eyed Demon]], they argue. John promises to hold off until Dean recovers, but actually summons the Yellow-Eyed Demon and makes a deal - his life for Dean's.
