Joscelin's mouth drops open as he watches the bird--Ginia--show off her new tricks.

"Shit," he breathes appreciatively, eyeing the blades. Once he's confident she isn't about to shoot more steal at him, he approaches the sword and nods at the bird, asking for permission to touch the blade. It certainly looks real. The blade has buried itself several inches into the dirt, and looks deadly sharp from his perspective standing a few feet away.

"That's...an interesting trick you have there."

It certainly answers the question of what a good a sparrow can do in open combat.
