"But you said you were brothers."

<We adopted him.>

"Then shouldn't you share parents?"

<No.>

"Poor orphans."

<We are not orphans.>

"But you don't have parents."

<We never had parents. So they did not die. So we are not orphans.>

"Still sounds orphan ish. Maybe aphan?" 

<No.>

"I think it's apt."

<You are mistaken.>

Seal suddenly makes his face lose all expression. "I am the Morrigan. You are mistaken."

Now Michael is upside down and being shaken.

As a child who lives underwater and regularly tussles with children larger and stronger than him, Michael is not entirely unfamiliar with this. "I am the Morrigan. I will hold you upside down now. I am the Morrigan." 

And now he's spinning, much faster than he ever has. Still upside down.

When he's dropped, he's looking very woozy, and actually grinning. "At least I have sensible pants ideas. I am Morrígan." Too dizzy to talk now.

And he's upside down again.

He just looks at her and giggles. It's a strange, musical sound. 

"I am the Morrígan, I will hang you upside you down over and over."

And now Stan is upside down again and they're both being shaken from side to side. Occasionally hitting their heads in ways that will conveniently not cause any brain damage.

Basically invulnerable and immune to motion sickness.

Michael does not like being hit in the head.

The remaining children take up their sword. Aside from Maurice who is telling them to stop being mean to his little sister.

Fine.

She screams.

In their heads.

It is exactly the most unpleasant thing any of them has ever heard in their lives.
