Oh, Brother! Exclusive Supernatural Casting News

Jake Abel

Is there a third Winchester sibling among us? It certainly would seem so, and Jake Abel (Threshold) is playing him, TVGuide.com has learned exclusively.

Abel has been cast on the CW's Supernatural as Adam Milligan, an 18-year-old whom Sam and Dean meet in an episode titled "Jump the Shark" and airing April 23.

Adam, viewers will learn, is the by-product of a little somethin'-somethin' that big daddy John enjoyed during one of his demon hunts. Upon eventually being told by a onetime paramour of Adam's paternity, John paid the lad the occasional visit. Never, though, did John alert Sam and Dean to Adam's existence, nor vice versa.

As such, it will be ... um, interesting ... when the two Winchester boys we know and love come to know the boy they (nor we) never knew. You know?

Yes, Supernatural fans. It's near-blasphemous to introduce a new bro. Do you think he's just a poser? Some demon's grand idea of a major mind-boink for Sam and Dean? Or is this kid not kidding around? I'm sure you have plenty to say, and you know where to say it.

Do you think Adam is the boys' actual half-brother ... or something/someone other?
