"Marooned" finds our heroes of CW's 'DC's Legends of Tomorrow' in deep space and some captured by space pirates. That leaves the unlikelist of action heroes in Professor Stein to save them. Meanwhile, we get flashbacks to Rip's training as a time master, and Heatwave becomes irritable. In one preview, executive producer Phil Klemmer describes Thursday's episode and what it means going forward.
PIRATE ATTACK -- After receiving a distress call from another timeship stranded in space, Rip (Arthur Darvill) decides to answer the call in order to use the other ship’s computer to track Savage (guest star Casper Crump). The team is suspicious and warns him this could be a trap but he moves forward with his plan. Ultimately, the team was right and they have to battle time pirates. With most of the team captured, it is up to Professor Stein (Victor Garber) to rescue them all.
