He can sing the grass up tall and fluffy for Catherine and then check very carefully that they're alone before any hair-grabbing.

Down on the soft goes Catherine and wherever her fiancé wants goes Rebecca's head and it prickles just the right amount, enough to remind her what to do but not enough to really hurt.

He is so, so delighted that that's the right amount. 

She is delighted about kissing.

Kissing is pretty great! Kissing someone when you can read their mind about how exhilarated they are is even better! Pulling someone's hair is really something! He possibly gets a little carried away kissing!

Well they're not married yet buuuuuut they will be tomorrow assuming he was not making that up?

" - hmmm?"

"- sir?"

He pulls her shirt back down.

Oh right he's reading her mind. Did she think something offensive? Or maybe he's just not in the mood anymore for unrelated reasons.

No, no, just remembered you'd want to wait. Forehead kiss. 

Forehead kiss! It is nice. "Thank you sir."

"I would like you to get good at noticing when you want to wait, so I can notice."

...over the course of the next day? She is not sure that can possibly be what he meant.

It is not what I meant. I meant in general.

"...aren't we getting married?"

"Yes. Tomorrow."

"...we don't have to wait after that, sir, I was not a very good nun but I am pretty sure about that part."

Forehead kiss. "Is that the only reason you can think of why you might ever possibly want to wait?"

...

...

The first few days after giving birth would be kind of dicey for certain things but it's not like if he wanted she'd fuss about it...

...

If Catherine or future siblings of Catherine needed her presumably he could figure that out? Maybe this is a very convoluted way of asserting that Rebecca is responsible for allocating enough of her attention to childcare.

Snort. "No - the other Rebecca likes having servants to help with the kids, we can arrange that..."

Oooh that sounds really convenient!

...

Yeah she has no idea what he meant then.

"So - if something is hard or unpleasant or scary for you, and you notice, then I can decide whether I want to change things so it's not as hard or unpleasant or scary. If you don't notice, then I have less control over that."

...maybe his mindreading works strangely and he can't just tell if she is scared unless she draws mental attention to it. "Yes sir."

Sigh. Snuggle.
