Last Refuge

"Last Refuge" is the twelfth episode of the first season of DC's Legends of Tomorrow, and the twelfth episode overall. It aired on April 21, 2016.

Synopsis
The team is targeted by The Pilgrim, a deadly assassin who wants to erase the Legends from the timeline by killing their younger, non-superhero selves. As a protective countermeasure, Rip decides Sara, Snart, Rory, Professor Stein and Jax 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.
