"But it would've meant they were less distressed."

<Yes.>

"Do you understand why that might be considered more desirable?"

<Yes.>

"Then why not take that onboard in future?"

<Because I do not care.>

"Most would not consider that an excuse, child."

Indifference.

"This discussion is not over."

<I am aware.>

"I don't intend to sound mean, but this is important, for you and Maurice. You don't want to make your brother unhappy, do you?"

<No.>

"Then consider in future that caring, or at least doing a decent imitation of caring, for others might maximise his chances of happiness."

<I can see the future. He will be upset that I do not care about his mothers, but he will prefer knowing this is true to being lied to and thus believing otherwise. I will minimize the distress of others when this makes my brothers happy. By the time Maurice wakes up there is only a small chance this will still be a problem.>

"...Good girl."

"At least you're quiet."

<I do not speak.>

"I was speaking figuratively, little one. Do you understand?"

<Yes.>

What follows is a lot of tests. MRI scans, X-rays, DNA and blood tests, some tentative examinations of their powers....

She is opaque to MRIs and X-ray scans. She has no blood to speak of and her interstitial fluids do not have anything recognizable as DNA.

Her powers are straightforward: she has extremely versatile, extremely powerful, extremely granular telekinesis; she can see a few hours into the future with very precise detail but mostly sticks to probability distributions; and she has an always-on psychic "sound" which she can modulate to cause people to think certain things and uses to communicate. She is deaf and blind but her future sight is a good enough substitute. If she uses her first two powers too much she is temporarily disabled—or so she informs them after some prodding, as she refuses to demonstrate the effect.

Levi is physiologically very similar to his sister. However, he seems to have all the usual human senses, in addition to his ability to perceive water for about a mile around him. He can manipulate water with a fairly fine degree of precision, and he can accelerate himself to very high velocities, leaving water in his wake. Then there's his ability to duplicate himself when submerged in water.

He can also shapeshift.

"What?"
