Overview
The team are called in to investigate when a lifeguard is eaten by a Mosasaur at a swimming pool. Cutter discovers that they are dealing with a mobile Anomaly when the Mosasaur and the lifeguard's vomited remains appear at a reservoir and a cellar floods and is invaded by a Hesperornis. The rest of the team also learn that Helen is alive and on the other side of the Anomaly, and so Cutter is forced to go through and confront the woman his wife has become.
