Changes

When going after [[Abaddon]] and the demons loyal to her, Sam arms himself with the knife, but is overpowered by three demons. However, [[Gadreel]] takes control after Sam is knocked out, overpowers the demons and kills them with the knife rather than his powers so Dean can explain away their deaths to Sam without Gadreel having to reveal his presence to him.[[File:DeadDemon.jpg|thumb|right|350px|[[Dean]] kills a [[demon]] by driving the knife through it's its neck.]]
