Arya ducks, curling under her coat so at least the smaller shards of concrete won't pierce her skin. One manages to strike her upper back, and there'll be a bruise there soon enough, but it doesn't deter Arya. She's had worse.

Diplomacy clearly isn't going to work here. Arya wonders what green-Bruce wants, other than to smash things and roar really loud.

That gives her an idea.

She scrambles back down to the sidewalk and runs a good ways in front of him, shouting as she goes.

"Follow me! This isn't any good for smashing, it's all too small! You need something bigger! Like caves! All the rocks you could ever want for smashing are there!"

Arya isn't sure if that'll work, but it's worth a shot.
