Oliver Queen has a bone to pick with Prometheus. In "Who Are You?", the "Arrow" mid-season premiere, Green Arrow will come face-to-face with his new, yet deeply personal nemesis -- and this time he won't be alone. A slew of new photos from the episode show Oliver and Felicity confronting the dark archer in a warehouse.

When the show returns, Prometheus won't be the only one with a vendetta. In "What We Leave Behind," Prometheus tricked Oliver into killing Felicity's boyfriend Billy Malone. Now, Felicity is on a mission to take Prometheus down, and it looks like she's evening willing to go into the field in order to do so.

Curtis "Mr. Terrific" Holt also appears in the photos, though fellow Team Arrow member Ragman is nowhere to be seen. Artemis also doesn't show up in the photos, though that is less of a surprise, seeing as she betrayed the team in the mid-season finale.

As the title suggests, "Who Are You?" will also deal with the mystery of Laurel Lance's return. Though these photos don't offer any new clues as to how she came back, a mid-season premiere promo strongly hints that she was Earth-2's version of the character.

Starring Stephen Amell as the Emerald Archer, “Arrow” airs at 8 pm ET/PT on The CW. The series also stars Emily Bett Rickards, David Ramsey, John Barrowman, Willa Holland and more. “Arrow’s” fifth season returns to the CW on January 25.
