Episode 15 - A Traitor

Previously... The Maunsworth Research Facility is still under investigation for the plane crash caused by the American Speers and his clandestine group. His assistant, Gutteridge, working with an unknown agent within the Maunsworth Facility has placed a computer virus on the Base's systems, manipulating the experiment data in an attempt to shut down the Standing-Point Project. Awkward eccentric Thomas Sullivan throws himself into his research, and finds a new friend in Susan Moranne, a librarian working on the Base. Grace Palmer and Commander James struggle to understand the nature of the Heavenfield, while fending off the air-crash investigation, but the future for the Standing-Point Project looks bleak. Alex, having returned to the Heavenfield, and the Exile Fortress, discovers the group are becoming ever-more fanatical. He is forced by their leader, Dr. Henschel, to return to the Maunsworth Base with the intention of murdering Grace and Thomas, thus destroying the British Research Project. He and his companions fly back through the Heavenfield in one of the prototype FieldShips. They infiltrate the Facility, but Alex is overwhelmed by visions and cannot bring himself to harm his targets. He retreats back into the Field, but two of his companions are lost – Krisz is killed by Thomas' bodyguard Sanders, and Yuri is shot, perishing back in the Field. Amidst the chaos of the Heavenfield, Alex is once again visited by the Demon Girl, but escapes, and makes his way back to Petre's FieldShip. They take off and head back for the Exile Fortress...
