Mmm, yes. As advanced as Luthien feels like teaching. 

Wonderful.

Delightful, wonderful girl. 

...Probably she should have a conversation with her about marriage, since Beren doesn't remember that they are.

Later, before they get all the way there.

They have an entire half the year to mosey.

Beren, though, might need the marriage talk sooner rather than later, going by how eagerly she's throwing herself at Luthien. Just maybe.

She broaches the topic over breakfast one day.

"So I'm not sure how much you know about elf marriages..."

"...Elves don't get divorced? That's about it."

"Marriage is, ah, a physical act, not just a promise."

"So - you can't get divorced?"

"...Are you telling me this because you want to ask me to marry you?"

"That, and also if we keep going as we have been, a marriage seems inevitable."

Heeee!

" - Wait you can get accidentally married?"

"Only if you're very irresponsible."

She giggles. "How do we get married?"

Luthien explains, giggling.

More giggles, and - "That doesn't sound onerous at all."

Pause. 

"...I'm doing this all wrong."

Pause, and she kneels at Luthien's feet, taking her hand. 

"Luthien of Doriath, my lovely Ellin, light of my life, song of my heart, I have no title to give you, no land nor worldly possession, just the strength of my arms and the truth of my love. Will you make me the happiest person in the world and give me the honor of being your wife?"

"Of course I will, my darling Mygwainor."

She laughs and stands, kissing her betrothed. 

Engagement kisses!!

The best kind so far! 

They are very good.

But married kisses might be better.

Well, there's nothing in Beren's culture saying you need a long engagement period...

That sounds like an excellent tradition.

Kiss!

She's ready as soon as Luthien is. 

Now seems good.

No sense in waiting to find out what married kisses are like. 

(Intense kiss.)
