While on their way to the Xindi council, Archer and crew encounter an Enterprise ship from the future that warns them about an unstable wormhole.
T'Pol and Reed lead a team on a mission to obtain information about the network of spheres inhabiting the Expanse; Archer and Hoshi stand before the Xindi council; the Sphere Builders reveal themselves to members of the Xindi council.
