During their last hunt together before [[Mary Winchester|Mary's]] death, Mary and the [[Apocalypse World]] [[Bobby Singer (Apocalypse World)|Bobby Singer]] took down this [[wraith]]'s nest. This wraith somehow managed to survive and escaped.

After Mary's death, the wraith attended her memorial, disguised as a [[hunter]] that was friends with Mary. Unlike the other hunters, the wraith did not raise a toast to Mary and simply stood in the back with his arms crossed, smirking. Also attending the memorial, Bobby recognized the wraith from the hunt he had taken with Mary and flung a hatchet into the wraith's head from the side, killing him.

As the wraith's body was dragged out by the shocked hunters, Bobby ordered them to retrieve his hatchet for him and explained to [[Sam]], [[Dean]] and [[Castiel]] his and Mary's history with the wraith. Bobby guessed that the wraith had been present for the memorial to gloat about Mary's demise to Bobby's great anger. Castiel pointed out that Mary would've appreciated that she got a hunter's memorial complete with a [[monster]], something that Bobby agreed with.
