Church is in Recovery Mode since Caboose activated armor lock and disabled their movement (except him because his Mark V armor is out of date). Church and Tucker then get out of Armor Lock. While in Sandtrap, Washington, Doc, and the Meta found Epsilons body.
The Reds are also stuck in Armor Lock, but they think they're dead. They talk to Church and agree to not attack the Blues, and F.I.L.S.S. gets them out of Recovery Mode.
