Uh. That depends on what she's into.

...sex? Probably. Her alts are into that.

Quelle surprise. But seriously, even if they have a solid guess on which role - and he should maybe not assume they match, some templates have more variety than others - there are miles of difference between, like, "digs elaborate ropework and calling you Master and needing permission to eat Skittles" and "enjoys fireplay and getting slapped for being a brat and weeklong orgasm denial" and those are just literally things she picked by clicking six times on the first google result for "random kink generator".

Uh.

She has an alt who liked being held prisoner and all of them seem to like being stolen by alien princes?

Is he actually going to be able to cope if she likes being held prisoner or kept in a locked box at the foot of his bed or something.

I love her!

That seems maybe premature! It may be that she should wait till we find another human you who can cope with the range on sub interests that exists! They didn't have Skittles in 1805 but they had lockable boxes!

I - if she was okay with my reading her mind so I knew she wasn't suffering -

Some of them are into suffering! Some of them might be into suffering yet not into mindreading!

Your planet is so weird!!! I think being into suffering is a different kind of suffering than the kind I am worried about.

How do you know?

I don't. 

Like, you could get lucky, but it is completely possible to have flat-out incompatible situations going on and I can in no way guarantee you that Rebecca is not, in Eclipse form, one of those edgeplay types who likes getting put through the wringer as bad as possible because it feels so good to stop, or something.

Beka's into way more intense stuff than her Macalaurë, I will ask her what she thinks I should do.

And he does. 

(Her Macalaurë has gotten the message from his alt and now visits her every day.)

Being visited is so great! (Does he have opinions on whether she should go get her free will revoked.)

He wonders if there's a way to get marriage but not oaths. If there's not she should maybe wait until she has a teleport so that nothing horrible can happen.

She's not in a huge hurry. Anyway her approach to the thing where she is into intense stuff is to tease her Macalaurë about it till he does it anyway! And then being conspicuously delighted the whole time! She doesn't mind having her mind read and bets that's template-consistent at least mostly.

"That sounds pretty workable. But would you be happier if he'd - had more warning in advance and required less teasing into it -"

"Nah he makes awesome faces when teased."

"Oh good. Okay." And he skips happily off to Lórien to wait for his Rebecca to be resurrected. 

Do you want me to spot you in case it's obviously not going to work from the word go.

Yes, thank you.

- you report in later in a state I'd describe as "optimistically freaked out".

He giggles. I'll take it. All right.

And this Rebecca will be able to breastfeed fine, they were careful about that, and wakes up in a similarly cheery Lórien.

She is delighted by Lórien! She feeds her baby! She goes wandering about and bows to the apparent singing angel and sits down to listen!
