Weeks pass, and he doesn't catch a single card.
When cards become active, he goes looking. They just disappear before he gets there.
He's getting worried, and he's not sure he's satisfied with Kero's explanations.
He tries to focus on school.
Well, then they can head outside.
"Jump, carry us wide and far, moving faster than a car."
Whee.
They eventually come to a copse of trees outside a neighborhood.
He leads her through the trees to a large suburban home.
"Here we are. My mom should be home right now. We probably won't catch my dad."
"Sixteen."
He unlocks the side door, and leads her inside.
"Mom, I brought a guest."
Well isn't that nice to know.
"And you go around hunting cards to prevent the apocalypse?"
"Reading, going out, watching movies, walking around town, doing things with people, more recently figuring out what-all I can do with that card."
"Figuring out the cards can be pretty time-consuming. Magic is a pretty good priority to have."
This must be his mother, descending the stairs.
"Hello, Alistair. Who is this?"
"She's a sorceress. She found a Clow card recently, and she's been using magic for years without help."
"You poor thing. Having to figure all this out without a family who understands. Do your parents know?"
"My father left us 'cause of it, my mother knows. And she's basically the only family I have."
"Mom, what she was really looking for was advice on how to use magic. She's mostly been guessing, and she wants to know more about the cards, and what she can do without them."
"The most important thing a beginning sorcerer can do is discover her strengths and weaknesses. You'll want to discover what your magic is uniquely suited to."
"Magic that belongs to you is easier to use than magic that isn't. Anything that you've discovered on your own is likely to be a specialty."
