Mel is keeping her head down, trailing near the middle of the caravan, keeping her bags extremely close at hand (her charms are in there. It won't be automatically disastrous if they're discovered, but it might be).

She's working herself up to trail after the two probably-Wizard-spies who joined the caravan earlier when suddenly the ground isn't there anymore. 

Mel falls with an 'eep', instinctively curling around her bag to reduce the chance of her charms getting too jostled.
