Here's what u gonna do in the Jonah quest:
Talk to him and read his mind, he'll talk about the giant whale... Then go to the sea side shrine, and close to there there'll be a whale skeleton and a girl moving in there, talk to her and tell her that whale skeletons are interesting, then she'll give u Jonah's necklace, and she'll ask help to find some info (if you read her mind u'll find out she's the crazy dude-who-invoked-a-demon-on-broken-valley sister, and get the password to their rich family moneh), give Jonah the nacklace back, choose a shitty reward and get a book from him, give the book to the girl and everyone is happy!
