"He is already angry with me. I worry that if you ask this of him, he will become wroth with you as well, where you currently are in his good graces. He needn't GRANT the boon, either. If you ask him for something he has already said must be denied... he'll be angry. I don't think we've really SEEN him angry, not furious. He cursed a woman to turn into a dove. His own sister in law.
Wouldn't it be better to ask a boon that will help you on your journey? Or to smooth the way in your new life?"
