2x9 - DC's Legends of Tomorrow

When Damien Darhk and Malcolm Merlyn try to capture Rip Hunter in 1967, they create an Aberration big enough to draw the attention of the Legends. However, when the team arrives they discover that Rip has no memories of his past due to “time drift” and is just a graduate film student. After trying to convince Rip of who he was, they discover that he possesses an incredibly powerful artifact known as the Spear of Destiny, which the Legion of Doom is after. Ray and Nate realize that the Aberration has also affected them personally making it difficult to help the team. Meanwhile, Rory asks Stein for help and makes him promise to keep it a secret from the team.
