Traveling through time to protect history warrants plenty of unforgettable adventures. But those once-in-a-lifetime opportunities also make it difficult to maintain a healthy relationship, a lesson Ava (Jes Macallan) and Sara (Caity Lotz) learned the hard way in Monday's actioned-filled episode of DC's Legends of Tomorrow.

It's pretty fitting that the Arrowverse's zaniest series tackled Lucha libre, a genre of wrestling characterized by competitors in colorful masks who perform daring high-flying moves, the week of WWE's WrestleMania (which is basically the Super Bowl of wrestling) since they have so much in common. Both shows have set themselves apart from the crowd with brazen storytelling and a carefree attitude that has catapulted them into a league of their own.

Owning up to that, this week's episode of Legends, titled "Lucha de Apuestas," found the crew in Mexico City in 1961, where escaped fugitive Konane (Darien Martin) had been hiding out as the masked wrestler El Lobo. The Legends intended to return him to the Time Bureau for escaping captivity until Mona (Ramona Abish Young) raised questions about the footage of his jailbreak. Zari (Tala Ashrafi) confirmed that the video was doctored in a cover-up by Hank Heywood (Tom Wilson) and the gang quickly changed their tune, pitting Sara against her girlfriend Ava in the process.

While Sara believed the edited footage pointed to the greater issue of a security breach at the Time Bureau, Ava was more concerned with capturing the mystical creature at all costs and those differing opinions culminated in a huge blow up over how each side handled the situation. Feeling betrayed by Sara, who opted to help the escaped Kaupe at the risk of her girlfriend's job, Ava promptly told Sara she's "done" with their relationship and gave her the boot. While this argument may have broken them up for the time being, showrunner Phil Klemmer says you shouldn't give up hope for a reconciliation.

"I don't know if I even consider them broken up," Klemmer told TV Guide. "They had a fight. I don't think that one fight is enough to destroy a couple as strong as Sara and Ava. They're both obviously fighters, and I don't think either of them is gonna let go of what they had easily."

"I feel like their breakup hopefully felt like a tragedy and not manipulation because like we did want to make it about something," he continued. "It wasn't like somebody cheated. We really wanted to make it like, 'Oh man, they really just have different outlooks on the world and different obligations.' We're gonna spend a lot of time trying to build back what they lost in that moment."

Sara and Ava might be down but they're not out just yet. For Klemmer, their relationship is a grounding presence on a show that barely exists in our reality, so it's being handled with great care.

"We have so many things that are just so flat out outlandish on our show. But with Sara and Ava's relationship, we wanted that to be the thing that lived in the real world. [Legends] is all over the map and so we wanted to level the genre of the show with something that felt more true to life. Everybody knows that Jes [Macallan] is gonna be on the show next season, right? We're gonna do something with them and hopefully we're not gonna do something that feels silly or goofy because we have enough of that on the show," he said.

Legends of Tomorrow airs Mondays at 8/7c on The CW.
