Plot summary
Fitz explains that he has traveled from their original timeline to this new one using the Quantum Realm. Deke decides to remain in the new timeline to help send the others and the Chronicoms back to the original one, becoming the new leader of S.H.I.E.L.D. When they arrive back in the original timeline, Fitz helps Simmons remember him and the life they lived while they were building the time machine, including their daughter Alya. Coulson, May, Mack, and Daisy infiltrate the Chronicoms' ship to rescue Kora and confront Nathaniel, who transferred Kora's powers to himself.
May and Kora combine their abilities to give empathy to the Chronicoms, ending their assault. Daisy fights Nathaniel before destroying the Chronicoms' ships, killing him and Sibyl. The agents find Daisy in space, and Kora revives her. One year later, Fitz and Simmons have retired to raise Alya; May is a professor at S.H.I.E.L.D.'s Coulson Academy; Mack continues to lead S.H.I.E.L.D., with Yo-Yo as one of his top agents; Daisy is exploring the cosmos with Sousa and Kora; and Coulson decides to travel the world.
