Melinda May meets Robin, now and elderly woman but still plagued by visions of past, present, and future. Robin and her fellows, led by Voss, make a home in the ruins of the Zephyr.
Voss's team brings in Coulson, Fitz, Simmons, Daisy, and Deke after their rough landing in the trawler. After a joyful reunion, the team gets down to business trying to figure things out.
Fitz and Simmons investigate a mysterious device which turns out to possibly be a time travel machine that needs the obelisk that sent them there -- a part of which is found in the hold.
Deke is upset when he sees the fragment, however, as he recognizes it as belonging to his father, who would never give it up. When he confronts Voss, Voss hits him and attacks Daisy, determined that she not return and destroy the past.
When he's unable to kill Daisy, he instead stabs Robin, so she can't impart important information.
As she's dying, Robin reveals that Melinda raised her as her own after the destruction of Earth and tells May exactly what needs to be done to save the world.
Back on the Lighthouse, Mack, Yo-Yo, and Flint locate Fitz's hidden cache of weapons and supplies. Unfortunately, Kasius decided to punish the humans for their misbehavior by setting Roaches on them.
Working together, the trio kills the roaches and begins freeing the humans.
