Now that they've proved themselves to be a nuisance, "DC's Legends of Tomorrow" are under fire from the Time Masters -- and the Time Masters are ready to play dirty. In "Last Refuge," they begin to target the Legends' younger selves. Several new photos from the episode show the team encountering themselves from an earlier point in the timeline as they attempt to prevent an assassin from killing them.

RIP'S BACKSTORY IS REVEALED -- The team is targeted by The Pilgrim (guest star Faye Kingslee), a deadly assassin who wants to erase the Legends from the timeline by killing their younger, non-superhero selves. As a protective countermeasure, Rip (Arthur Darvill) decides Sara (Caity Lotz), Snart (Wentworth Miller), Rory (Dominic Purcell), Professor Stein (Victor Garber) and Jax (Franz Drameh) need to kidnap their past selves first before The Pilgrim gets to them. Coming face-to-face with the younger versions of themselves proves to be both a physical and emotional challenge for certain members of the team who would rather forget their past. Rip tells them he has a refuge for their precious cargo -- an orphanage that raises future Time Masters and where he himself grew up. Rachel Talalay directed the episode written by Chris Fedak & Matthew Maala (#112). Original airdate 4/21/2016.
