It would be fascinating to hear about how he mediated between his mother and father and the many inventions he skillfully built. I would like to hear about the events when Hephaestus cursed his mother Hera’s chair and how they sent everyone to talk to him to get him to release his mother and how Dionysus got him plowed drunk and kidnapped him, then he ended up gaining a spot among the Olympians as well as the hand of Aphrodite. Think that it would be an interesting story to hear of the construction of all the thrones he built for all the gods and what intricacies were included in them and techniques used while assembling them.
As for a long ride with a god I think would be disastrous would be a ride with Hades, I cannot see that ride coming to a very good end.
