When Astra and Spooner find themselves as stowaways, they learn that Constantine is still chasing the Fountain of Imperium and find themselves in 1920s Texas. With the rest of the Legends stranded, they come up with a plan to get help by using Rory as bait that will also help reunite him with something that is special to him. Meanwhile, Spooner learns some information about her past that she wasn't expecting.

The group discovers a member did not make it to safety inside the subway car. Surrounded by walkers, going back out into the tunnel to search is a guaranteed death wish. All eyes are on Negan as the rule of survival shifts. It is no longer No Man Left Behind. The motto now is We Keep Going. With very little ammo and energy remaining, the group must ready themselves as the walkers have found a way inside the subway train. Meanwhile, Daryl is in his own intense hellish situation trying to find Dog and finding more than he expected; and Yumiko challenges the process at the Commonwealth outpost, which threatens her future and that of Eugene, Ezekiel, and Princess.
