The Legends lost one of their own during the crossover event with Arrow, The Flash and Supergirl last week.
Martin Stein (Victor Garber) was caught up in gunfire as he tried to save his friends. Gideon (Amy Pemberton) was unable to save him and Martin pleaded with Jax (Franz Drameh) to take the serum to separate their connection and let him die.
Reluctantly Jax did it and then had the difficult time of having to deliver the news to Stein’s family.
Elsewhere Sara (Caity Lotz) hooked up with Alex Danvers (Chyler Leigh) and helped her get over her relationship breakdown with Maggie (Floriana Lima). Leonard Snart (Wentworth Miller) from Earth-X decided to join the Waverider.
The mid-season finale is Beebo the God of War. The team get a surprise as they investigate an Anachronism in a Viking settlement. Sara starts to worry when Damien Darhk shows up.
