The war against the British Men of Letters is coming to a head.

Obviously Sam and Dean weren’t going to die after Mr. Ketch left them on Supernatural Season 12 Episode 21, but it looks like their circumstances haven’t gotten any better.

According to these photos from Supernatural Season 12 Episode 22, Dean has been left to deal with Toni at the bunker. But is she working with him now?

It also looks like Sam is raiding the British Men of Letters compound… and with a familiar face in tow.
