Yvette looks very much like she would like to start shouting at Cerberus again, but this time she inhales sharply, shuts her eyes, and counts to ten in her head. Very quickly.

Once this is done: "I apologize for not being clear in what I was asking," she says, a little bit too formally. "Give me a minute, I'll go get paper, and then could you please be so kind as to list them out for me so I can write them down?"

"Okay."

She then summarily ignores him and looks at Windy.

"Thanks," she says, the formality dropping a bit because she's not talking to the person she's upset with, "Hopefully I'll be able to practice with you before a card turns up, but uh - thank you for being understanding about this whole thing." Pause. "And I know it's not your fault, about the - card thing."

She resolutely does not look at Cerberus. She does not look at Cerberus. It's incredibly tempting, but she doesn't.

She nods again, smiling.

Yvette smiles back, and then wills Windy back to card form.

She picks up the card and puts it with Libra, then walks (she does not stalk, she is careful to not let herself stalk) off to get paper.

Blair doesn't seem inclined to talk to Cerberus at all while she's gone.

Cerberus doesn't know what he did wrong.

Ugh.

"You know her knowing all that she possibly can about the situation is very important, right?"

"...yes?"

"You... don't really act like it? It is sort of like you are doing the minimum requirements for explanation instead of showing initiative about what she needs to know, and you're not checking to make sure that she can actually absorb the information, or understand it in the greater context of what's going on, so she has to piece together tidbits instead of having a good foundation. She has to build the foundation herself."

"I'm not a teacher," he admits. "I'm a guardian beast. I was born knowing things."

"I'm sorry you have to do things you're not good at and weren't made for," says Blair, "but you're also the only one we can actually talk to that does know these things. Do you want help trying to figure out how to teach?"

"...yes?"

"Okay. So I think it's a good idea to focus on the overall structure of how magic works - have you told her all of the information about basic principles?"

"I don't know basic principles. I only know about cards, and a little bit of what Clow showed me."

"That's okay, you don't need to know everything," says Blair. "But I think you're underselling what you do know. You know that there are two types of magic, and that the cards are sorted into one or the other, and what they're all capable of and their personalities and mannerisms. That's not nothing."

"That's true. But I don't know what else is important. And I don't know all about the cards, only what they told me."

"Okay, well, I'll help you with figuring out what's important. Are there - sets of rules the cards follow? Or categories that they sort into besides sun and moon?"

"Yes. They are divided in seven groups: Windy, Earthy, Firey, Watery, Light, Dark, and Nothing."

Yvette returns with a pencil and a notebook newly made empty by strategically ripping out pages devoted to algebra.

She raises an eyebrow, but doesn't ask.

"Okay, and how many cards are in each group, and what is implied by being in a group?"

"Nine cards in each of the element groups, eight in each of the attribute groups, and Nothing is alone. Cards in a group will trust her more and be more powerful if she controls the leader card."

... Yvette sits down to write this! It seems appropriate! She makes a table for all of the cards and their card groups.

"All right, that makes sense." He glances at his sister for Are You Absorbing This Information. ... His sister finishes writing a thing, then looks up and nods. Right, okay.

"Does being part of a group do anything else, besides being more powerful and trusting if she has the leader card?"

"I don't think so."
