"Given the reason we are here, anyone being useless in a war makes little sense," It would make sense if most people had some useful skill. Even if not all of them are cut out for direct combat. Course, anyone from her world would know something about combat. Just the way things were, and it was nice he wasn't talking down to her as much as others on the ship.

"My personal guns are energy weapons, powered off me. But my soul is worthless in a fight, I heal people." She didn't bother to pull out her gun to show him. She gestured to the gun she pulled out, "This is a' Energy weapon, but it appears to be based on a projectile weapon and modified. Can't kill, but for me I'm good with that so long as nobody means to kill me right now." She could get a proper lethal force weapon later on, when she's going into a fight that's sure to be them or her. Wandering around the ship she just feels better with something she can use to put someone down.
