Yeah. Useful, too. He's been very inventive lately. 

Rebecca attempts melodic dictation.

He is happy to sing it as many times as are needed.

And then she has it written down, with an approximation of the Quenya lyrics too.

He has more songs! ...it is possible he doesn't sleep.

Rebecca needs to take breaks to feed Jeremy. And also needs sleep.

And also they should see what their sudden twin daughters have gotten up to.

The twin daughters are climbing trees with an anxious house elf spotting them.

Awwwww. "Hey, girls, it's way past your bedtime."

"THERE IS NO BEDTIME," says Catherine.

"I SLEEP WHEN THE SUN IS ATTACKING ME," says Kat.

"That doesn't seem very fair to the elves. You don't have to go to sleep but you do have to stop doing things that require supervision, okay?"

"Night is for being outside!" insists Kat.

"I have not showed her all trees!" cries Catherine.

"You can show her some trees tomorrow."

"ALL TREES."

"I can sing you to sleep. Want to see?"

"You do that all the time," says Catherine.

"I can do it with magic."

"Singing magic?" asks Catherine.

"Yeah!" says Kat. "That's true."

"Oh." Catherine wobbles her way down the tree.

He scoops her up. Would Kat also like to be scooped up.

Yes.

He scoops them both up and takes them to Catherine's room and duplicates Catherine's bed.

"That one is mine," Catherine says, pointing at the preexisting bed.

Kat blinks at the bed. It is a bit more elaborately bed than she has usually slept in.

"You can arrange it to your liking," he reassures her.

"Gray," says Kat.

Now her bedding is all gray.
