The Winchester boys are back in action! After a year in purgatory on Supernatural, Dean is finally reunited with Sam and brotherly love never looked so good.

In the first promo for Season 8, we not only catch a glimpse of the heartfelt reunion, but we also get some serious knowledge dropped on us: Not only is there a second Word of God, but it contains a way to close the gates of Hell — forever!

Partnered up again with the adorable prophet Kevin Tran, the brothers decide to go on the offense for once and get rid of those pesky demons once and for all.
