Although Daniel Blakemore has died accidentally, the Army still wants to know what the corporal may have told Professor Monaghan and his team. Monaghan himself feels a certain amount of guilt about Daniel's death and is having trouble sleeping. He even imagines seeing him from time to time on the the street or seeing a hooded faceless figure following him. He can't explain what is happening to him. He determines that he's probably being followed and suspects the military of being behind it all. (thetvdb.com)
