12. Before the Blood

Complete story — includes the ending

Sean and Katie catch up aboard the Seraphim, with Katie telling him she put herself in a coma and left the Aruna via the escape pod 23 months ago. Sean reveals that the Seraphim is currently unable to communicate with Earth, and he tries in vain to re-enable the antenna system. Molly and Ryan make contact with the French crew that found Katie. Molly receives a memory-boosting shot from Dr. Barton to help her identify the codes she entered while having the vision of her and Marcus' baby. It is revealed that the codes sent the Seraphim off course and hurling toward Earth. Ryan feels that Molly is the only one who can go into space and intercept the space station, but she doesn't want to go. Molly meets her "son", who comes to her house. The words he speaks to Molly convinces her that she must go back into space. At the Humanichs lab, Charlie discovers an 87-minute gap in Ethan's programming, and Julie confirms it occurred while Odin was watching Ethan. She discovers Odin is Gavin Hutchinson, who was once arrested for an anti-technology plot. Aboard the Seraphim, Sean feels that he and Katie must leave the station via escape pod. While making preparations he finds Katie's corpse in the escape pod and realizes what he interacted with was not her. The door to the escape pod closes, and he sees "Katie" through a window. "Katie" tells the trapped Sean, "It's okay," as the Seraphim falls toward the Earth.
