7. The Totally Excellent Adventures of Mack and the D

Complete story — includes the ending

Stuck in 1982, a despondent Mack spends the next year alone in grief. Deke checks in on Mack occasionally, and eventually convinces him to come see Deke's new band, The Deke Squad, which include Olga Pachinko, Roxy Glass, Cricket and twins Ronnie and Tommy Chang, which performs 80s' classics that have not been written yet. Deke reveals that he has secretly been training the members of the band to be S.H.I.E.L.D. agents, and that Coulson's consciousness has been saved on a hard drive. Meanwhile, Sibyl's consciousness also survived, and she uses a lonely programmer to construct a crude body for herself. She then creates new "hunter" robots that kill the programmer before invading the Lighthouse in search of the time stream that Sibyl uses to predict the future. Mack helps Deke and the new agents defeat the hunters, unaware that a small robot escaped with the time stream. The Zephyr re-appears long enough for May and Yo-Yo to reunite with Mack and Deke. The latter recounts the past year's events to May. The small robot takes the time stream to Nathaniel, who survived the collapse and is now working with Sibyl.
