Well it does make sense that Hook can prove he knows her by telling Emma some things about her that complete stranger wouldn't know. That could make her start believing him. But Ariel can always take of her bracelet and turn herself into mermaid in front of Emma's eyes :D (though she didn't see August's wooden leg so maybe this wouldn't work)
