Caity Lotz revealed that next week’s Season 2 finale of “Legends of Tomorrow” was extra hard to shoot.

In an interview with The Hollywood Reporter, Lotz said that there were a lot of technicalities involved in the finale, and that’s one of the reasons why filming the episode was a big challenge for the cast and crew.

“There’s a lot of technical, CGI things and it’s very difficult to shoot,” Lotz, who plays Sara on the CW series, said. “I’m really curious to see how it all comes together. It’s crazy.”

Despite the filming obstacles, Lotz said that fans will be shocked by what will go down in the finale. “It’s going to blow everyone’s minds of what’s happening in the finale,” Lotz teased.

As previously reported, the Legends will try to put back reality as it was in the final hour of the season. In the trailer for Season 2, episode 17, the team returns to 1916 France in the middle of World War I to stop the Legion of Doom from ever getting the Spear of Destiny in the first place. But in addition to dealing with the Legion, the Legends must also convince their past selves that they are allies and not enemies.

The Legends’ primary objective in the finale is to destroy the Spear of Destiny once and for all, but as the synopsis for the episode states, destroying the relic comes with a huge consequence.

Also in the finale, Sara will be reunited with her sister, Laurel Lance (Katie Cassidy). “It’s only one scene,” executive producer Marc Guggenheim told TV Insider of the reunion between the siblings. “I have to give a shout-out to Katie Cassidy. … She’s spectacular in it. It’s a scene we’ve wanted to do since the beginning of the season. We really wanted to get Sara and Laurel back together.”

“Legends of Tomorrow” Season 2 finale, titled “Aruba,” airs on Tuesday, April 4 at 8 p.m. EST on The CW.
