Next week's episode of "Legends of Tomorrow" will see the team return to the future, but this time they'll be faced with a moral dilemma. The promo for the episode, "Progeny," lays out the problem clearly: will the team kill a 14-year-old boy before he grows up to become bloodthirsty ruler? New photos from the episode see Rip Hunter (Arthur Darvill) getting quite close to the boy in question, going so far as to go undercover within the ranks of the enemy.

You can check out the synopsis and promo for "Progeny" below. "Legends of Tomorrow" airs Thursdays on the CW at 8 PM EST.

RIP CROSSES THE LINE IN HIS EFFORT TO SAVE HIS FAMILY - Rip (Arthur Darvill) tells the team they are headed to the future to take out a powerful ally that Savage (guest star Casper Crump) needs in order to conquer the world.  However, when Rip reveals the ally is a 14 year-old boy (guest star Cory Gruter-Andrew) who will one day grow into an evil dictator, the team is split about the morality of killing a child, even if it does save the world.  Meanwhile, Sara (Caity Lotz) talks Snart (Wentworth Miller) through a rough patch and Ray (Brandon Routh) learns something that could impact his future with Kendra (Ciara Renee).  David Geddes directed the episode written by Phil Klemmer and Marc Guggenheim (#110).
