"Thank you."

An hour before sunrise then next morning Hohenheim is still asleep, head on the desk. A pile of papers sits finished on the floor beside him, neatly tied by cloth strings.

If he's not awake by the time they should be leaving, she'll wake him; otherwise, she will let him lie.

... yep, still asleep.

Does shaking his shoulder work?

He jumps and starts to transmute his chair into something. 

"Relax. It is time to depart."

He freezes. "... yes. I'm sorry if I startled you," he says, putting the chair back.

"You will have to pose a significantly more present threat than that to startle me."

"Good. Why don't we get going?"

She is ready to leave.

Hohenheim is a bit tireder today. At slower hours he looks ready to nod off. 

Mrs. Shahidi, on the contrary, is full of energy. She's ecstatic at all the new business she's able to do because of their efforts.

Occlus works steadily, as indefatigable as ever.

That steadiness will see her through the next few days. Especially since the notes are far more detailed than the previous ones -- they include a primer on chemistry concepts Hohenheim thinks are important and expects that Occlus maybe does not know, they explain the properties of some of the shapes that appear in arrays, they include hundreds of diseases that didn't appear on the pages from which she worked yesterday.

The chemistry refresher is useful. She draws on her archeological expertise to catalogue and categorize the types of arrays, and separately, the diseases.

A week later Nur gets too close to her papers with a boiling pot of water and an emotional state to match.

A painful jolt of electricity, and a careful nudge to insure he stumbles back rather than forward-

"Take a moment to think before you do something that will irritate me."

"You're corrupting Mother!" He screams. "Ishvala forbids the study of alchemy!"

"I am not your mother, nor am I her teacher. Go bother someone related to the problem you are attempting to solve."

"You shouldn't want to learn alchemy. It led our people to ruin. It made hundreds of miles into desert. And now mother wants to pretend to be Xingese." He spits. 

She zaps him again, harder this time.

"Do not attempt to dictate what I am allowed to learn. Cease speaking, and leave me, or you will regret it."

"What are you doing to my son?"

"Teaching him a lesson about the difference between people he can afford to approach with less than overwhelming force and the people he cannot." She pauses a moment. "The muscles spasms should subside in five to six minutes."

"It is not your place to discipline my boy," she screeches, then whips over to look at Hohenheim. "Control your apprentice."

Hohenheim is very visibly uncomfortable. "I'm sure we can come to some sort of agreement. If Nur is unhappy with our presence here he can arrange to be elsewhere while I help you."
