Plot summary
S.H.I.E.L.D. and Daisy independently investigate the figure, an apparent ghost of a woman named Lucy Bauer, both concluding that she worked at an abandoned facility, Momentum Energy. Daisy confronts Reyes again and he once more overpowers her. Restraining her, Reyes searches Daisy's belongings and discovers her research on Momentum. He leaves and Daisy escapes her restraints. As Mace plans to officially announce S.H.I.E.L.D. as a legitimate organization again, the infected May grows increasingly paranoid, seeing all people as monsters and eventually attacking other agents.
Mace restrains May with his Inhuman strength and promises to take care of her. Mack and Fitz arrive at Momentum to find more ghosts, who attempt to blow it up with them inside. Ghost Rider intervenes, destroying one of the ghosts, and Daisy arrives to stop S.H.I.E.L.D. from apprehending him. Rather than rejoin S.H.I.E.L.D., Daisy agrees to work with Reyes, believing that the actions of both the ghosts and the Watchdogs may be tied to him.
