Sorry, Gon, Lambert's looking elsewhere, judging the crowd. He personally thinks it wouldn't get much notice if they did step on someone, but given that he's the one hitching a ride...

"It's not like a it's a secret," Lambert shrugs. People ask on the radio often enough, and it feels like he's explained what a witcher is a hundred times, but right now, isn't the time to explain it once more.

"But fine, maybe I've got something. Close your eyes!" He digs his fingers into a pocket, producing a small, paper-wrapped package that he lobs overhand, into the crowd ahead of them. Well before ever hitting anyone, the fuse ignites and the flashbomb goes off with a loud bang, making people yell sharply in confusion and stumble back from the sudden noise and flash of light in their midst. At least it clears the path a bit, but it's probably not the outcome Gon would have preferred regardless.
