what is tree-ears consequence for being brave

I think the consequences are good. When a commission from the emissary has a possible chance of ending up with Min, Tree-ear takes this opportunity to prove himself. The journey ahead is a treacherous one that even Min cannot tread thus Tree-ear decides to navigate it for a chance to secure the commission. He is attacked by robbers on his way and breaks all the vases that were to be delivered to the emissary. However, rather than just return back home he picks up a single shard with hope than it will be enough. And indeed manages to get the commission for Min with the piece. Tree-ear exhibits such determination and hard work that seem out of this world for a young mind like his.
