SPOILER WARNING: This article contains major stories for "A Mad Tea Party," the midseason finale of Batwoman.
"Crisis on Infinite Earths" is finally upon us. In "A Mad Tea Party," the midseason finale of Batwoman, The Flash's Nash Wells made a surprise guest appearance that may very well have kick-started the worlds-ending crossover event.
After the devastating events of the midseason finale, Batwoman smash-cut to Central City. In a tunnel deep beneath the city, Nash stood before his handiwork. He had chipped away at the tunnel wall, revealing a metal door with strange symbols underneath. As he gazed at the door, a timestamp revealed a jump to Dec. 9 at 11:58 pm, the day the Batwoman installment of the crossover is slated to air.
"For so many years, I've traveled across worlds, across the multiverse, to do one thing: kill you," he whispered. "And now we're here. You saved my life."
A disembodied voice responded. "Submit, and begin your life anew," it boomed.
"Show me," Nash said with a smile.
"The knowledge is within you," the voice replied. At the sound of it, the symbols on the door illuminated, inviting Nash to approach.
He did so and, after a moment's hesitation, tapped the symbols in a certain order. When he finished, he took a couple steps back and waited. The door suddenly burst open, bathing him in a white light. He tilted his head back in ecstasy. Then the light enveloped him and dragged him forward, eliciting a scream. The door slammed shut after him, with teaser text promising the story will continue in "Crisis on Infinite Earths."
As revealed in October on The Flash, Nash has been hunting the Monitor for some time now. However, if Marv Wolfman and George Pérez's Crisis on Infinite Earths is any indicator, it probably isn't the Monitor behind that door. Nash may have just released the Anti-Monitor into the Arrowverse, which could transform him into Pariah and launch the events of the Arrowverse crossover. Notably, The Flash is due to sacrifice his life on Dec. 10, which is shortly after this flash-forward takes place.
In the comic event, Pariah inadvertently summoned the Anti-Monitor and thereby launched the events of the comic. Pariah was one of the greatest scientists on his world but, as a result of his experiment to view the creation of the universe, he caught the Anti-Monitor's attention. The Anti-Monitor used Pariah's experiment as a tool to free himself from a prison made by his brother, the Monitor. The Monitor snatched Pariah away from his world just before the Anti-Monitor destroyed it. The destruction of Pariah's world gave the Anti-Monitor enough power to begin his quest to annihilate the multiverse.
Batwoman will return in "Crisis on Infinite Earths," which begins Sunday, Dec. 8 at 8 p.m. ET/PT on Supergirl, then continues in Batwoman on Monday, Dec. 9 at 8 p.m. ET/PT and in The Flash on Tuesday, Dec. 10 at 8 p.m. ET/PT. After the winter hiatus, the crossover will conclude on Tuesday, Jan. 14 in Arrow at 8 p.m. ET/PT and in DC's Legends of Tomorrow at 9 p.m. ET/PT.
