The CW has released new photos for 'Fellowship of the Spear', the fifteenth episode of Legends of Tomorrow's second season.

The episode finds the team undercover in the middle of World War I, and it's clear that they aren't alone. Several of the photos show a confrontation between Mick Rory/Heatwave (Dominic Purcell) and Leonard Snart/Captain Cold (Wentworth Miller).

It's unclear if the pair really are reuniting face to face, or if this is just another one of Mick's hallucinations. But Snart's return was teased in the recent promo for 'Fellowship of the Spear', making that moment one that will definitely be worth keeping an eye on. Click through to our next slide to see the gallery of images, and check out the synopsis below:

IT’S WAR — The Legends must devise a plan to retrieve the last remaining fragments of the Spear of Destiny from the Legion of Doom. They find themselves in France at the height of World War I faced with the knowledge that they must destroy the mystical object. They enlist the help of a soldier by the name of John Ronald Reuel Tolkien (guest star Jack Turner) and find that the Spear is leading them into the heart of the war. Meanwhile, the team must all resist the temptation of the Spear, and the return of a former teammate.
