The guard misses the keyhole, and it rebounds into his skull, killing him instantly.
Jesus fucking christ, what the flying fuck. Bob is terrified ans now he fall to the ground into a fetal position and crying. he keep saying to himself, "not again, not again, not again". And suddenly, he's latent telekinetic powers rip the door down and fling it across the room like it was nothing.
He leaned against the door in fear, but then feel out into the hall! It was unlocked!
Licking the gun doesn't give Bob any clues... except the taste of gunpowder and warm metal. Looking down the hall there is a door with silhouettes walking around inside. To the right there is also another prison cell door.
After hiding the guard's body in your cell, knocking on the other door gives you screams in response.
