It's time for Supernatural's Winchester brothers to electrocute a few friends once more.

The Khan worms will return in "The Things they Carried," and the Winchester boys will deal with them they only way they know how - electrocute the infected victim until the insidious worms meet their demise (see photos above).

Unseen since Rufus' death in season 6, the Star Trek inspired monsters will rear their tiny little heads once more on March 18. Innocents will become killers as the worms infiltrate their victims' minds, and Cole (Travis Aaron Wade) will soon find himself in the same boat.

Cole will team up with Sam (Jared Padalecki) and Dean (Jensen Ackles) prior to his brain hijacking and, luckily enough, Dean will be on hand to try and zap the sci-fi creation out of the former Marine. Lets hope electrocuting people doesn't make the Mark of Cain overly excited.

Unfortunately, there is no telling what Cole may do before the hunters' intervention. Another host, played by Supernatural alum Richard de Klerk, will be in attack mode, will try to inflict his murderous desires on Jenna (Michelle Morgan) despite Sam's protection, and it looks like the brothers will have their hands full defeating friends and foes alike.
