Racing along the rooftops, occasionally leaping to swing 'round a flagpole or somersault to a new building, a little pale girl with long white hair was busy keeping an eye out for people she knew. Or at least someone interesting! And that was definitely someone interesting. He could be from her time, wearing what he is. Not one of her people, but perhaps someone acquainted with them.

She hops down to a lamppost some few yards further ahead in his path, staying out of immediate reach of those blades.

"What are you doing?"
