"Any opinion on decor?"

<No.>

"You?" she asks Levi.

"I like fishes!"

She smiles. "I hope you're content with wallpaper."

<I can keep fish alive.>

"...Not sure what you mean there," says Mary.

<Without water.>

"Wouldn't that be cruel?"

<Fish do not experience suffering.>

"I meant pictures of fish. Real fish are for eats."

<That can also be provided.>

And now they all experience the hallucination that goldfish the size of footballs are swimming around the room.

Suddenly, Levi is a lizard again, and trying to eat the fish.

Well she can use her telekinesis and song to make it seem like he is in fact eating the illusory fish.

"You can just create living things like that?"

<They are merely illusions.>

"So you're tricking your brother?" asks Mary, warily. 

<I am enriching his make-believe game.>

"What?" says Levi, mouth full of pretend fish.

She repeats it.

He spits out the imaginary fish. "Michael says I shouldn't let you do stuff like that."

<Like what?>

"Mind controlling me."

Confusion. <I was not mind-controlling you.>

"But you changed the way I thought."
