Inwardly amused, Odin attempted to answer each question honestly and straightfowrad. Youth. Far too much energy and too many questions.
"You let me go first out of respect, both as your elder and your king. However, were a woman present, she would go first. It is simply a sign of good manners."
"No, we aren't going to Midgard. And Heimdall is right."
"No, you are not in trouble."
At that last, Odin made a mental note to check around to see if there was something that sparked Hermod's question, though it seemed nothing more than natural worry when a parent asked to speak with a child. Maybe Odin needed to spend a little more time with the boy if the only times he showed up made his son worried about being in trouble.
"As I said, I've something to show you." Having reached the doors, Odin stepped out of Frigg's hall, turning the corner without waiting to make sure the boy was with him. Curiosity, if nothing else, would keep Hermod close. Without looking at his son, Odin motioned to the beast before him.
"His name is Sleipnir. A gift to me from Loki. Seems he had reason to be away for the last year." Odin would wait for Hermod's reaction before proceeding with his plan. Should the boy not take an interest, beyond the bizarre number of legs, it would little matter. He needed to show enthusiasm for the creature, and eagerness, and if that happened, only then would the Valfather extend his offer.
