Seat 23E remained empty as Chia waited for takeoff, sucking on a peppermint the flight attendant had given her. The only empty seat on the plane, she figured. If nobody arrived to take it, she thought, she'd be able to fold the armrest away and curl up there. She tried putting out a negative mental field, a vibe that would keep anyone from getting on at the last minute and sitting there. Zona Rosa was into that, part of her whole girl-gang martial arts thing. Chia didn't see how you could seriously believe it would work.
