Changes

When [[Sam]] and [[Dean]] encounter [[Meg]] in Chicago and realize she is linked to the [[demon]] that killed [[Mary]] and [[Jess]], Dean calls John. He later arrives and Dean embraces him warmly. John reveals that Meg was trying to kill him because he is hunting [[Azazel|the demon]] with the intention of killing it, something he isn't sure is possible but which he is determined to try. Just as he reunites for the first time in years with Sam, greeting him warmly and showing some regret that it has been so long, they are attacked by [[daeva]]s and are nearly killed before Sam manages to dispel them with flares. Afterward, Dean supports John when he says it is too dangerous for them all to be together, and they part with John promising that the fight is just beginning and that they will be a part of it.

[[Dean]] reveals to [[Sam]] that in 1989 when John was hunting a [[shtriga]], he left Dean and Sam alone. When the shtriga attacked Sam, John returned just in time to save him. In the present, John sends them the coordinates to Fitchburg, Wisconsin, knowing the shtriga is there and that killing it is unfinished business for Dean.
