This is very good because those emotions are positive! It's so implausible of him to on top of all his other good qualities like her and want her and be able to let her know it. She cannot quite fathom it and she wants it so badly and probably it'd be distracting and totally throw off the mood if she said 'I love you' and she doesn't even know what those words mean so she doesn't but she kisses him and tries sending impatience right back in his direction though she's not sure if that works.

If she's not just failing to hedge him out but actively shoving thoughts and feelings out for him then he can definitely pick them up. 

Leareth is thinking, deep enough that he's not projecting the thought itself, that he probably loves her. He's also confused about all the shades of meaning in that word, but - in the end the part that matters is the reality of it, which is that they're married and they just pulled off a fairly impressive state wedding in two weeks together, and he's so, so grateful to suddenly be in a world where this is even a possibility he can reach for. 

Leareth, of course, has no discomfort at all about reaching for something he wants and can see is possible.

He's so happy.  

...there turns out to have been some good reason for the advice to take it slowly your first time or it'll hurt, but she doesn't actually care because she is very happy and married and Iomedae was right and everything is wonderful and she is too distracted to doubt all these very implausible opinions of hers, right now, and maybe for a while.

There are a lot of hours left in the night, too, for people who have Rings of Sustenance. Though it was a really long day and Leareth has been out of Lesser Restorations for a while, and well before the time they usually go to sleep he's out of energy to do anything more than flop and cuddle. 

:It is a word with complicated meanings: he sends, :but - I think it is accurate enough, now, to say I love you: 

- it probably can't ruin everything if you're just saying it back -

:I think I probably love you too.:

Nothing seems to be ruined at all! Leareth keeps holding her and quietly projecting contentment. There are still problems to be solved, and endless work ahead, they're not done, but all of that can wait until next week.
