JT dislikes the girl from the start, made obvious by the sudden scowl. The gum-smacking does not help one little bit. Disgusting. Already her fingers are itching to grab her knife and lodge it in the girl's decorative face.
However, Carcer's confusion makes her giggle. That's right, money was different on the Disc, wasn't it? Her parents rarely spoke of the Disc (Nny hadn't been too fond of it), so there were several things she had forgotten. She'd have to explain it to him later.
And when the girl's eyes widen upon seeing the blood, JT smiles again. "What's wrong, miss? Is there a problem?"
