A large thud in the back of the bus.

The sound startles the newbies behind you and as a born leader you order them to shut up. Being all dark in the hanger and the bus, you stay alert for anything out of the ordinary. When the scene becomes silent again a faint sound is heard. You immediately observe the sound as a gas like when you cut a gas line.

You are correct but before you come to realize your downfall, you are knocked out by the gas. What was thrown into the back of the bus was a smoke grenade, incapacitating all the occupants on the vehicle besides the driver, who secretly donned a gas mask.

Hours pass by and you are not in the bus anymore.
