"No problem, let me know when you've got it specced."

And he hugs his brother and congratulates him and grumbles about how he'll possibly come up with anniversary presents with demon in-laws and looks utterly delighted for them both.

"I'm sure you'll think of something," she assures him. "We're going to tell the engineers next--oh, hell, I'm going to have ten fathers-in-law, that'll be interesting."

She has ten cheerful and congratulatory father-in-laws! Who will consent to stop their work for an engagement party!

Excellent, she is in favor both of parties and of engineers taking a break without having to be dragged.

It's a lovely party. Demons make party planning fairly unnecessary. The depressing Maglor turns out to have a non-depressing and non-20th-century-pop repertoire and does some fast-paced romantic songs from his Valinor for them.

Awesome.

"We should at least invite our alts," she tells her new fiancé.

"Oh, yeah -" hey, magic Tyelcormo, Edie and I are having an engagement party, want to come?

He conveys this to Idaia.

"That sounds fantastic, actually. ...how long has it been since Edie came up last?" She fumbles for the fancy future clock.

"Wasn't paying attention, sorry."

She finds the clock. "Three hours," she announces. "Anyway. Let's find out what she put in those pretty wardrobes."

Pretty clothing! Pretty, suggestive, futuristic, weird clothing but he can roll with that. It will be a challenge to get dressed while not letting go of Idaia but he's very motivated.

Idaia briefly cries when she finds a copy of the dress she arrived in Valinor in.

Hugs. Well, they were already hugging, but more hugs.

Yes good.

I think I'm going to ask her for at least some of our wedding presents.

Sounds fair. We inspired them to get married, that's kind of cute.

It is! I am quite pleased to have done this for her, every one of me should have one of you.

Indeed. We shall go around the multiverse matchmaking.

Mhm! Remember when I brought up the possibility of alts, back in Valinor, and you said it was wildly improbable?

No, actually, but I believe you -

You said you'd want to be sad about it if you hadn't met me and I framed the question in terms of hypothetical alts, saying if there was a me who didn't have a you I didn't want to make her sad about it.

Oh, yeah, that does sound familiar. Well, now we can hopefully go around introducing them.

Yep! Nuzzles. Okay, we are both clever people who managed to get dressed despite logistical constraints, let's go downstairs to the party.

He picks her up. 

They go downstairs to the party.
