"That sounds lovely," she beams.

So they're off to Tirion! It's about an hour's walk from the house. It's a very pretty walk, of course.

She might miss most of the landscape because she's too busy gazing adoringly at her husband instead.

He knows it all by heart. Course, by this point he knows her face by heart too, and it has not encouraged him to stop.

Presumably her face is still more novel than the place he's lived his whole life.

More novel. Also prettier. Also more responsive to him, that bit's excellent. Valinor is not going to blush if he gazes at it adoringly enough.

That's true, it isn't. And she is. And they're ~married~ so it's not just her face that he can observe.

They are so so married!

What kind of PDA is acceptable here?

Social conservativism. They can hold hands but people'll think it's a bit much, really, unbecoming. At festivals people do all sorts of things, but then they have the excuse of a lot of alcohol.

Damn, holding hands is a bit much? That's some pretty severe conservativism. Well, is anyone looking?

Nope! Here they are holding hands. 

If no one's looking, no one will be shocked if she steals a kiss.

No! But then they reach the gates of the city and should probably cut that out, people are staring.

Yes, she will refrain from gratuitously scandalizing them. Not that they wouldn't deserve it. Prudes.

He is married and people can see it in his eyes so he makes eye contact with all of them.

...Can people see it in her eyes? She's not an Elf and her species doesn't natively do this...

They're not having much trouble guessing who it is I married but I don't think they can see it in your eyes.

Are they liable to make weird assumptions or just chalk it down to 'I'm not an elf'?

Just that. It makes sense that if your race doesn't do that it still wouldn't if you married one of us.

Oh, good. She still doesn't go out of her way to make eye contact with any of them.

Want something to eat? Tirion's got loads of nice things -

Sure! She's not super hungry, but she's curious, and she does have room.

Then try these! And these! People occasionally ask him what he's thinking and a couple of them glare but mostly it's going over well.

She successfully restrains the urge to make rude hand gestures at the glaring people. The food is delicious, which helps because self-distraction.
