Jean scowls. "That's stupid. So unless you know the gun, there's really no way to tell if the safety is on or off?"

The more Reiner tells him, the more Jean thinks guns are overrated. He might just stick to his rapier and whatever bludgeoning weapon he can find handy. Still, he should probably learn about the safety on the most common guns. Then, at least, he can make sure they won't go off while he's bringing them to Reiner and Bertolt.
