goodbye with his daughter Dana as well as the rest of the O.S.I.R. team and leaves a goodbye tape. Beginning with the following episode, Matt Frewer is removed from the opening credits and Nancy Anne Sakovich receives first billing. In episode 18 of the season, "Regeneration", presumed dead Conner Doyle returns and reveals he was pulled out of the building before it exploded and then spent three years in Siberia where he was held prisoner in a research facility in order to study an alien parasite that he had contracted during the original mission. He returns to aid the team in which they investigate "Project Regeneration", where a genetically altered female has the ability to heal herself, but with alien DNA that will take over and make her violent. Lindsay finds out that her cells were used to create Lilith, and that she retains all of Lindsay's memories. Conner suggests a plasma transfusion where Lindsay's cells could be introduced into Lilith to enhance her human side. During the transfusion, it's revealed Lilith is pregnant, Conner has alien DNA, and he is trying to save their alien child. Peter and Anton release a toxic gas into the secured lab, killing Conner and Lilith. In the fourth season finale, "Stone Dreams", we learn Mia Stone has been subject to a secret experiment conducted by Anton Hendricks when she first arrived to the O.S.I.R. The experiment aims to determine the impact of paranormal investigation on the investigator.

During the test, Anton hypnotizes Mia and gets her to remember past events that then are reflected on the monitor.
