The jam-packed "Westworld" Season 2 premiere raised a lot of questions, including one that revived an intriguing fan theory.

There are spoilers from "Westworld" Season 2, Episode 1 ahead!

When the Man in Black (Ed Harris) awoke in premiere episode to the aftermath of the massacre, he spotted a character familiar to fans: a wolf. The creature was sniffing around the carnage, much as it had been in flashbacks we saw in Season 1. Some viewers were particularly struck by its appearance -- not so much because it had appeared on the show before, but because they thought they knew it from another show. Fans on Reddit, Twitter, and other social media sites were quick to suggest that the "Westworld" wolf is actually Nymeria, one of the "Game of Thrones" direwolves.

The theory -- which also cropped up after Season 1 -- is interesting because if Nymeria is indeed wandering around "Westworld," some fans say that Westeros from "Game of Thrones" could be one of the parks that Delos Destinations owns.

It would be one serious, surprising twist, that's for sure. Imagine if Cersei (Lena Headey) was really just a vacationing woman getting her twisted kicks and Jon Snow (Kit Harington) was actually a host. Hmm... It might actually explain some things.

Still, we don't really think it's true, and the fans talking about it on Twitter don't seem to, either. Most are just expressing surprise, confusion, and delight at seeing what looks like a Stark direwolf wandering Westworld.

"Westworld" airs Sundays at 9 p.m. ET/PT on HBO.
