Phil Coulson,
Leo Fitz and
Robbie Reyes are trapped out of sync with reality, unable to interact with the real world, with no-one else able to see, hear or touch them. They are being drawn to another dimension, which Robbie describes as Hell, revealing that the Ghost Rider spirit has been there before. Killing several agents using his new powers,
Eli Morrow escapes, while the Ghost Rider spirit, unwilling to return to "Hell", abandons Robbie and instead possesses
Alphonso "Mack" Mackenzie, just as he learns Morrow was allied with the Chinese
Watchdogs, having recruited them to retrieve the ghost scientists and find the
Darkhold. Mack hunts down the remaining Chinese gang members, and
Daisy Johnson pursues him, unknowingly accompanied by Robbie, who convinces the spirit to return to him and help him exact revenge on Morrow, in exchange for Robbie continuing to serve as the spirit's host afterwards.
Melinda May decides to use the
Darkhold to rescue Coulson, Fitz and Robbie, and enlists
Holden Radcliffe to read the
Darkhold, but he finds the contents are too overwhelming for the human brain to perceive.
Aida suggests she reads it instead, revealing her android nature to May (and Coulson), and with the magical knowledge she learns from the book, she builds a machine that opens a dimensional portal, through which Coulson, Fitz and Robbie return. Meanwhile,
Jemma Simmons frees
Vijay Nadeer from his Terrigen cocoon by touching it, at which point
Ellen Nadeer immediately has her removed. Upon returning to the
Playground she reunites with Fitz, who learned of the deal
Jeffrey Mace made with Nadeer while out of sync. In an end tag, Aida secretly begins experimenting with her new knowledge from the
Darkhold, creating an artificial brain. == Production ==
