Last week on DC’s Legends of Tomorrow, Eobard Thawne (Matt Letscher) cemented the reality he had created–known as Doomworld–when he incinerated the Spear of Destiny. In this reality, all the Legends have their memory back except for Stein (Victor Garber) who is a loyal employee of Thawne’s, Rip (Arthur Darvill) and the Waverider are unknowingly shrunken down and sitting on Thawne’s desk at STAR Labs…and Amaya (Maisie Richardson-Sellers) was killed by Snart (Wentworth Miller) just as she was about to use the Spear to put things back to the way they were. Seeing no other way to make things right, Sara (Caity Lotz) proposed that they travel back to World War I and stop Mick (Dominic Purcell) from giving the Spear to the Legion of Doom–breaking the most important rule of time travel in the process.

“This Is Heavy”

In tomorrow’s season finale, ‘Aruba’, the Legends will risk time folding in on itself (and apparently erasing themselves from existence) to stop Doomworld from ever existing. “As [executive producer] Marc Guggenheim has said many times, and in shaming me for the fact that I’ve never seen Back to the Future 2 — I’m sorry, I apologize to everybody — from what I understand, this is a version of what happens in Back to the Future 2,” executive producer Phil Klemmer told Entertainment Weekly. “We’ve always wanted to break the cardinal rule. Obviously, from a mythology standpoint, it’s very exciting to imagine what will happen when we do the one thing that Rip told us never to do. But from an interpersonal perspective, it’s interesting to see how our Legends will interact with themselves.”

Over on The Flash, Barry Allen (Grant Gustin) has met versions of himself from several different time periods. For the Legends, however, this will be a first…and there’s a good reason for that. “Well, it’ll take at least another season to try to, if not fix, mitigate some of the destruction that we inflict on the universe in the finale,” Klemmer explains. “I just know, as a viewer, I would hate people if they made it too easy. It’s been 33 episodes of us being like, “You can’t do that, you can’t push that button,” so if it were too easy to undo the cataclysm, I would be like, “Oh, come on!” It’s not resolved this season. It basically is the propulsion that will take us into season 3.”

Looking Ahead

A little less than a year ago, the Legends met Hourman (Patrick J. Adams) for the first time when he arrived in 2016 and warned them not to climb aboard the Waverider, knowing their lives would be at stake. This time around, however, things aren’t going to be so black and white. “[…] season 3 is going to be totally different, it’s not going to be just fixing these simple aberrations and then moving on,” Klemmer said. “As our team is maturing, they’re going to be — next season — faced with questions of like, “What if putting things back to the way they were wasn’t good enough?” It’s always great when you have a conflict, when you have two equally valid points of view. That’s what you want on a show, because if everybody agrees, the show gets really freaking boring really fast.”
