It looks like things are coming to a head with the British Men of Letters in the two-part finale of SUPERNATURAL

In part 1 Sam and Dean are caught in a dangerous situation. Leading out of this week’s episode, we know that the brothers are trapped inside their own bunker — along with Toni — and will die if they don’t manage to escape. Meanwhile, Mary has been brainwashed and turned on her own sons. But it looks like we’re going to see an ultimate showdown between the Winchesters/their fellow American hunters and the Brits. Will this be the end of the British Men of Letters or will they turn tail and live to fight another day?

Meanwhile, in the second part of the finale Kelly returns and starts going into labor. It appears we’re also heading into a showdown with Lucifer over the fate of the nephilim.

Browse through photos above for the two-part season finale episode of SUPERNATURAL airing at 8:00 p.m. ET/PT on The CW.
