The Legends are heading back to World War I in the Season 2 finale of “Legends of Tomorrow.”

Earlier today, Maisie Richardson-Sellers — who plays Amaya on the CW series — shared a photo on Instagram with the caption “WW1.” In the snapshot, Amaya and Sara (Caity Lotz) are in nurse uniforms, while Mick (Dominic Purcell) and Nate (Nick Zano) are in soldier getups.

On Saturday, Zano shared a close-up picture of Purcell sporting the same outfit. In the caption for photo, Zano wishes Purcell a happy birthday. Click here to see the snapshot.

As revealed by Zano last week, “Legends of Tomorrow” is currently filming episode 17, which is the final installment of the show’s sophomore run. The episode is titled “Aruba.” It is directed by Rob Seidenglanz and is written by executive producers Phil Klemmer and Marc Guggenheim.

Aruba is a constituent country of the Kingdom of the Netherlands in the southern Caribbean Sea. While it’s likely that the Legends will be visiting Aruba during World War I in the finale, the title may have a completely different significance in the episode.

Interestingly, Aruba has been mentioned on the show before. When Gideon told the team that the next time aberration would likely take place in Bhopal, 1912 in Season 2, episode 1, Mick disappointingly said, “Why can’t it be Aruba, 2016?” Will Mick’s desire for a vacation in Aruba finally happen in the finale? Only time will tell.

“Legends of Tomorrow” Season 2, episode 17 airs on Tuesday, April 4 at 8 p.m. EST on The CW.

Meanwhile, in this week’s Season 2, episode 12 of “Legends of Tomorrow,” the team travels to 507 AD Camelot where Stargirl (Sarah Grey) is guarding a piece of the Spear of Destiny. While protecting the shard of the spear from evil Rip (Arthur Darvill), the Legends meet King Arthur’s (Nils Hognestad) wife Guinevere (Elyse Levesque) who helps them accomplish their mission.
