Enterprise starts experiencing effects of the spatial distortions pervading the Delphic Expanse, and falls victim to predatory aliens.

When Enterprise responds to a distress call from a Vulcan ship stranded in the Delphic Expanse, Archer and his boarding team are attacked by insane zombie-like Vulcans.

Archer goes to extreme lengths to save an abandoned nest of Xindi-Insectoid eggs ready to hatch.

Archer and Hoshi stand before the Xindi Council as T'Pol and Reed lead a team into the heart of a Sphere.
