He takes a deep breath.

"Okay."

It's slow, as he turns his tissues more human, watching Terel for reactions.

Nervousness. Is the reaction.

Eventually he's all blooded up.

"...It's. Managable. Mostly because you're my mate and it's very easy to think about how I must never ever hurt you."

"You'll get used to it. It helps if you're filled to sloshing with blood."

"Yeah, I'm getting that... It's a lot more stressful now than even a few hours ago. Practice in unfavorable conditions is a good thing. Though I wonder if there are magic items to suppress the sense of smell, or at least make clean air."

"I think you should probably get used to it before getting anything to suppress the smell, I only started after I knew I could stay around blood without snapping."

"Yeah, you're probably right... Doesn't mean I have to like it."

"It doesn't. I'm sorry."

"...I think I want to take a break from computer stuff."

"Okay? What do you want to do?"

"I don't know, really. Talk about some other field of science, but not in a seriously-working-toward-something way 'cause that's the thing I want a bit of a break from. Go over everything I learned in college about magic again. Make up a board game."

"Okay, we can do that. I can recite you stuff you taught me so you'll memorise it with your new brain?"

"Yeah, that'll do."

So he starts helping with that.

It's about three months of regular practice before Terel starts to feel confident about his self-control. He waits two more just because before wondering if it's about time to go back to society at large.

His family, possibly?

"There's something I want to do myself real quick, first. It shouldn't take long."

"—okay? Can I ask?"

"Hm, you might like it better if it's a surprise."

"Ooookay, then."

"So yeah, I'll be back in an hour. Two tops."

"Okay." Kiss! Very kiss. "I'll miiiiisssss you!"

"I'll miss you too! Be back as fast as possible!"

And he is back as soon as possible, with something smallish extra in one of his pockets.
