It should be fun. Aria is very curious and a bit silly and flighty, as fairies can be.
Hahaha, Belle is not entirely amused by being a doll (but she's SO PRETTY how can anyone resist?!?), but she probably went along with it for Papa. And their shop is still in business (barely) they just lost all their ships to a storm and are trying to get back on their feet. It's smart of her to stay in contact! :D
