Hadrian's investigation is able to determine that a Cylon agent or collaborator used an open hatch on the hangar deck to reach a small arms locker where a Marine guard was killed and the explosives stolen. Hadrian focuses on Chief Tyrol after the deck gang, in an attempt to protect Tyrol, concocts three different stories about where he had been. Eventually Hadrian goes so far as to question Adama, implying that Tyrol and Boomer are both Cylon collaborators. Stating that Hadrian has lost perspective and turned the tribunal into a witch hunt, Adama dismisses it and has Hadrian arrested despite the tribunal pointing out that he has no power over them. In the aftermath of Hadrian's arrest, the tribunal places the blame on Specialist Socinus who had confessed to leaving the hatch open under interrogation to protect Tyrol. Socinus is stripped of his rank and confined to the brig. Despite knowing Socinus is innocent, Adama refuses to intervene on his behalf.
