Lila and Jesper
Jesper's life wasn't particularly easy, and he was in at least a little bit of danger pretty much the whole time he was in the Barrel. But he'd gotten used to that, and was armed pretty much anywhere he went. He usually had a rifle, too, but it hadn't come here with him. He'd make do.
Since arriving, he'd been using his abilities a little more than normal. Not using your Grisha abilities wasn't good for you, and could literally make you sick, so he'd been doing little repairs inside the cabin where the Crows were living. It wasn't much, but it was enough.
"Alright, say it is Clay who finally snaps. How do you think he'll fight?" Most people here, after all, weren't armed.
