With all the poison they no doubt have lying around in their kitchens?
Yeah, I've been foraging in the garden here before. My own cooking skills are basically "spit and roast".
I doubt Odin's ever cooked anything beyond "spit and roast" in wilderness situations. It's not Frigg's hobby, either, though I'd be less surprised to find that he dabbled in it once. We just have cooks.
...Somehow I was not imagining that was in the top ten factors in his decisionmaking, although I suppose I could be mismodeling him.
This seems like an even worse criterion with magical soul bonding than it does in the standard case. I suppose you don't age so there's no concern about people's looks inevitably fading, but still. I pick up pretty people for casual flings but I'd need so much else going on to settle down.
The Quendi value beauty very highly. And - I think there's a common mindset that it's most important to desire your spouse, everything else you can get from other relationships, that you can only get there. Which of course wouldn't be true on Asgard. Bed, pretty children, someone on your arm for public appearances - if you don't actually like your wife that doesn't matter as much.
People are frequently monogamous on Asgard, at least by the time they get married. If I met somebody I wanted to marry I think I'd prefer it; I mean, I could probably make it work with Sigyn if I wanted to turn it into a romance instead of a friendship with benefits and he could never pull off monogamy in a million years, but it'd be a compromise. And it is considered horrible to be married to somebody you don't like.
