[I interpereted it more this way. The nobility god offered a kind of "embassy" type of "assylum" for those who ask for it before dying, so that their souls have a free ride away from the proper path of passing. This was a kind of tounge and cheek snub, as a kind of lover's rub. Nir the death goddess finds it irritating, which is why the nobility god thinks it's funny. However, this time the conflict of interest over you, and your "obligations", and in regard to the requirement fr both of them to maintain at least the illusion of free will in their servitors caused a horrible argument. My character only swore one oath, and has no allegiances to the nobility god. The only obligations he has to satisfy are the death goddesses'. Since the ghost was taking assylum, weird sent the whole embassy, in order to satisfy his contract. A technicality for a technicality. The road of the dead is NOT meant to transport physical substances. (You can't take it with you.) Further, the embassy table is meant to be in the world of the living. As a return rub, the death goddess sabotaged the embassy so that nobody sane would want to use it, (really, who wants to hear two lovers cooing/arguing constantly?) Then sent it right back where it came from. The ghost inside isn't really insane, just under a great deal of stress. The fact it saught assylum is immaterial, that its natural body died made it de-facto dead. Hugo isn't dead, because his physical body did not actually die. He's a serious catch 22.]
[As for the "flirtatious behavior" between the two, this is a common theme in mythology, with gods and goddesses having no higher authorities to answer to, they are often hedonists. See for instance, all the flings and infidelities in the greek pantheon. Nir is more accurately approximated as the sister of the goddess of childbirth, both having spheres that overlap with the circle of life. She has more incommon with atropos, the greek fate that severs the strings of men's fates. Athel's string was cut. Hence wierd's compulsions.]
