'Batwoman' on The CW: How the Nash Wells Scene Sets Up 'Crisis on Infinite Earths'

"Crisis on Infinite Earths," the latest Arrowverse crossover on The CW, is starting on Sunday, August 8, and this week's episodes of Arrow and The Flash are sure to give us more hints of what to expect from the four-episode series. Batwoman on Sunday, December 1, however, delivered the first major hint of what we can expect from the event.

Batwoman Episode 8, titled "A Mad Tea-Party," ended with a scene that saw Harrison "Nash" Wells (played by Tom Cavanagh) crossover from The Flash into its sister CW show. In the scene, he was seen in Central City, outside of the Eternium door, behind which is The Monitor (LaMonica Garrett). The character had been on a mission to kill The Monitor, but decided he could not go through with it. He said that as The Monitor saved his life, he would now spare him.

We then saw him "submit" to The Monitor in order to "begin [his] life anew" by approaching the door and hitting a sequence on its symbols. This filled the sewer the door is situated in with a golden light that sucked the character into it.

Though the episode of Batwoman did not reveal what had happened to Nash, fans of the Crisis on Infinite Earths comic books and those who have been keeping an eye on casting news think that this scene is setting him up as major "Crisis" character Pariah.

In the comic book series, Pariah is the scientist responsible for opening an anti-matter portal that allows the Anti-Monitor (also LaMonica Garrett) to enter Pariah's world and destroy it. However, Pariah himself is saved thanks to The Monitor. Though the character is pretty powerful, he is also powerless to stop the destruction of many worlds, which he sees get destroyed after he gains the ability to travel between worlds.

That this would also happen in The CW's version of "Crisis on Infinite Earths" was confirmed in an interview Arrow producer Marc Guggenheim had with ComicBook.com. He told them: "Basically... we're gonna begin the way 'Crisis on Infinite Earths' the comic begins, which is the destruction of various parallel universes. And the goal is for us to adapt key moments from the comic, those seminal moments."

As for what will happen in the remaining episodes of The Flash and Arrow until "Crisis on Infinite Earths" airs, The Flash showrunner Eric Wallace told a San Diego Comic-Con audience that the remaining episode of his show will "lead up to a very, very big twist at the end of the Bloodwork case that launches 'Crisis.'"

He also said of Pariah: "In the original miniseries, it's Pariah who is very much integral in releasing the Anti-Multiverse. For Tom to play such a pivotal character... it's just going to tear your guts out and make you cry."

"Crisis on Infinite Earths" stars Sunday, December 8 at 8 p.m. ET on The CW.
