Season 3, Episode 9:
The team have to deal with a herd of Embolotherium from the Eocene. Danny arrives with a mysterious woman called Eve who he first saw in the future; having rescued her from Christine Johnson, they endeavour to save everyone from the stampede. When the anomaly closes, at a campsite, Eve opens another anomaly to return the beasts and are all saved. Upon their return to the ARC, the team are shocked to discover that Eve is Helen Cutter in disguise, who takes Johnson hostage. Holding her at gunpoint, Helen steals the artifact, pushes Johnson through an anomaly to be butchered by future predators, and vows once again to stop the ARC's work from destroying the world. The team decide they must stop Helen before any one else gets killed.
