She attempts to conjure a hand-sized scale model of Abbadon!Luthien.

Yep, that is a Endorë Elf princess. Or half-Maia. Whatever. 

"...How does that even work?"

"You know, I have absolutely no idea. Maiar can look human, but..."

"If she's a princess maybe Doriath will have published something on the subject and we can ask Bar."

"Maybe, though from how our alts described their version I sort of doubt it."

"Point."

"Our world seems differently dysfunctional but I'm not sure how far that goes."

"Well, at least our Thingol doesn't have Alqualonde to ban Quenya and generally hate us over."

"Wait, really, you don't think he will? Maitimo snapped the binding on his daeva and then a lot of people died, I bet he'll consider that sufficient excuse."

"We can swear that I, the demon whose binding snapped, didn't kill anyone, and that the whole point of snapping my binding was to prevent exactly the disaster that occurred, and that he got me to swear oaths that reasonably substituted for a binding before snapping it. Truthfulness oaths are convenient."

"Perhaps someone - not me - can charm Thingol out of being a dick and then when Lúthien meets her foretold boyfriend Thingol will be like 'you'd better treat her right' or something and let it go."

"Perhaps a Maitimo. Although I admit I have to wonder what fool errand he'd send him on, given that we're not unstopping time until we can get the Silmarils back."

"I bet there are lots of ways to get a naive kid who's reckless enough to walk into Angband killed."

"Maybe if we deal with Morgoth quickly and efficiently and he doesn't grow up as part of a guerrilla band harrying orcs he won't be that reckless."

"He might not even exist, we might accidentally disrupt his great-grandparents meeting or something."

"Yeah, bit silly to worry on his behalf at this stage."

Indeed. Instead they should make out and drop the scale Lúthien and forget he exists - or will exist, maybe - entirely.

This is an excellent plan!

Rather leaves the post-party cleanup to Emily but at least it's hardly any work for her.

It is not. Although she'll spend the time also commiserating with her alt on sisters and their boyfriends making out at odd moments.

Well, their engagement party isn't such an odd moment. When the food and decorations have all turned into air the party disperses. Maitimo heads back inside and gloomily works on multiverse planning for the rest of the day.

"You need a nickname," Cam remarks apropos of nothing.

"...yeah, I do. Be a bit rude to keep going by Maitimo while all the other ones adopt one. Suggestions?"

"There's probably no sufficiently oblique way to turn 'only sane Maitimo' into a nickname, is there."
