What a lovely solution. What a lovely person. So, so glad we found you -

Me too.

Fëanáro fails to notice for several solid months. He also does not seem to have noticed Ferardrin and Leaf, and he's been very busy playing with the pieces for a spell that will let him conjure permanent things (not arbitrary material objects, but he wants to have that eventually). Rúmil is sort of vaguely optimistic he may be an adult before he notices.

I think that would involve waiting 38 years to have sex. Is that the plan?

I thought the rule was that if we expect hard enough that sex doesn't cause marriage and instead, formally and soberly deciding to get married causes marriage, then marriage will cooperate?

Assuming we can in fact manage our expectations like that, or at least you can, not sure if it matters if I do, yes...

I think so but we should probably wait until it's an acceptable outcome to us, at least.

Yeah. And assuming this doesn't take 38 years, he might notice. He might even pick up on it before then, he is only inconsistently oblivious about stuff.

So you want to think about how to tell him?

Better to have a plan and not need it than to go 'um'...

Yeah, true. Hmm. Do you think he'll be upset?

I'm not sure. He hasn't previously exhibited any objection to us being close...

He might take it okay.

He might. Or he might think it's weird or suddenly worry that we're competition for each other's affections or something...

...yeah, he also might do that. Hmm.

And I'm not even sure his alts would be particularly useful predictors.

None of them had quite the same relationship with me, and of course not with you.

Yeah.

I'm not sure that we can come up with a plan better than 'tell him and be reassuring'.

Yeah, maybe not.

Fëanáro announces he's visiting space Arda, gets distracted at the hop through Hell, and decides to stay and look around.

The stopoff point for Hell is in the middle of nowhere, a cute little terraformed and furnished planetoid with a few emergency type supplies for anyone teleporting in some kind of emergency.

Awwwww. Loki's teleport can't take him 'somewhere cool and exciting in this dimension' but his wizardry teleport can target for 'near people'. He goes near people. 

Now he is in a really really tacky city! Some of the individual parts of it have a coherent aesthetic to them but none of them agree. Everybody is a young adult human-looking person except for having gone through an ethnic blender, and they've all got bat wings, and some have more exotic cosmetic alterations beyond that too - tails, horns, hooves, scales, fangs.

His appearance attracts attention; he is promptly asked in six languages whether he speaks those languages.

He doesn't but he would really really love to learn! He will point at things and ask what they're called and start trying syntax to get their reactions!
