Supernatural's Cole will team up with the Winchester's for a very Star Trek-esque episode.

It appears season's 6 Khan worm will make a comeback in "The Things They Carried." Created by Eve, the monster caused Bobby to kill Rufus during "...And Then There Were None," and it will turn more good men into ruthless murderers during episode 15.

Sam isn't about to stop looking for a way to cure his big brother, but Dean will use the first post-Cain episode to take on a monster of the week. Lured by the recent murders, the Winchesters will head out to investigate only to meet up with Cole. Now aware of the world of monsters, the former soldier will join the hunt, although he may not make it back.

Cole will become an unfortunate receptacle of the Khan worm, and hopefully Sam and Dean can remove it (i.e. electrocute him to fry it) before Mr. Trenton meets an untimely demise.
