Spoilers for Peacemaker season 2, episode 8 follow.

It's been almost a month since Peacemaker season 2 wrapped, and DC fans from across the multiverse have been praising James Gunn, John Cena, and the whole 11th Street gang for yet again creating a heartfelt and hilarious superhero riff. But believe it or not, there's one other massive name that deserves praise for the Peacemaker 2 season finale, one that you might not expect to hear tossed around in DCU conversations.

That is, Game of Thrones creator George R.R. Martin.

Before we get into why he deserves some praise, though - you see those spoiler warnings, correct? They mean that we're going to be telling you exactly what happened in the finale of Peacemaker season 2. Don't say we didn't warn you. OK, let's get into it.

Things were looking up for ol' Chris Smith as the sophomore season of his titular show was wrapping up. He had been released from prison, and his pals had just founded a new peacekeeping agency in the weird world of metahumans. But little did Chris know that Rick Flag Sr. (whose son Chris killed, remember) had tricked him into signing his life away, "volunteering" him as a guinea pig to be placed in a newly discovered alternate dimension. This alternate dimension, which Flag calls "Sanctuary," is his and Lex Luthor's newest ploy to trap metahumans that can't be contained by Arkham or Belle Reeve.

It is also, funnily enough, a co-creation of George R.R. Martin.

That's right - decades earlier, Martin and co-author John Jos. Miller had come up with this particular 'prison dimension' for what would eventually become the 2007 DC Comics miniseries appropriately called Salvation Run. Writing in his blog at the time of the comic's release, Martin described his thought process in coming up with what would eventually make it into the DCU as Chris Smith's biggest obstacle yet.

"When Britain sent convicts to Australia," writes the Tales of Dunk and Egg scribe, "They were transported 'for the term of your natural life,' and that was the premise of our story too. There was no escape. The planet was in another galaxy, millions of light years away, accessible only by Boom Tube. We wanted to tell a story that would span decades."

Well George, considering that this story is having implications all the way out in 2025 (and beyond, probably!), we'd say the plan worked. 

Peacemaker is streaming now on HBO Max.
