I don't get this holotape, after having been through the vault. Voice 1 is the person who doesn't want them to commit suicide. WHY is voice 1 the one left alive at the end? He was the one not wanting the 5 to die. He wouldn't shoot the other 4, nor would he shoot himself. Apparently there was only one gun, yet I cannot find a gun in the vault entry room, leading to me to believe they had a gun each and voice didn't use his. Can anyone confirm that they found a pistol in the vault 11 entry room?
