The kid's leg was broken — like, really broken. Ben had no concept of how to deal with that, since he'd never been one for healing magic, and what basic first aid he knew was useless in the fog, anyway. His knowledge of human anatomy was only good enough to get him familiar with the basics of what lay beneath ladies' skirts, not where to put a bone after it had been broken. His own broken limbs had always been dealt with via magic, and while he was diverting his eyes and trying to pretend it didn't hurt as much as it did.

So rather than deal with that mess, he turned his attention to the troll again and watched one of the Ministry blokes run into the building everyone else had just been running out of. What was he planning? Ben had been far too distracted getting himself and the girl out of danger to keep track of what the scheme had been — he'd barely been able to keep track of the troll, which was a much more pressing issue where his immediate health and well being was concerned.

Struggling to his feet, Ben took one staggering step towards the ruined front of the sweet shop, where the troll was leaning in to follow the man who'd just run inside. "Uh," Ben said, still not sure what was going on. "What can I —" do to help, he was going to say, but was seized with another coughing fit, which racked his rib cage with more spasms of pain.
