There is a certain bookstore just one street out of the way of the path between school and Terence's house. In that bookstore a certain corner has a large pile of unceremoniously stacked books labelled '25¢ each'. Terence is digging through them for science fiction. Most of it is self-improvement books, or recipe guides, or trashy romance novels. The few sci-fi pieces he finds will probably be really crappy science fiction, but he still has to try.
He peers at it. "Never seen anything like that." Pause. "Oh, duck, Cerberus is in my body, isn't he."
"Duck? Anyway, probably, yes. Which is why we have to fix it as soon as possible. I don't think he'll deal with it gracefully. I can supposedly detect the loose cards while they're active if I meditate, so I'm going to do that."
He sits cross-legged, staff in hand but cards off to the side since he's looking for something else.
...well, he looks like he knows what he's doing. Whoever-it-is that's inside Cerberus' body will watch.
His meditative trance will come to him a little bit more easily than the previous day.
Looking like you know what you're doing is a valuable skill.
He carefully doesn't think about determining in which direction might he be feeling something that's not Cerberus-y, Windy, or Float. It really is getting easier.
That is probably the card. He gets as good an impression of where it is and where it's heading as he can, then snaps out of the trance. "I think I found the card. Heading toward the mall. Question is, do you want me to try and catch it immediately to get this fixed sooner, or go to your house and talk to Cerberus who's probably in your body?"
"Seventeen. They're strict about 'privileges' and 'decadence' and 'discipline'. Can we not talk about my parents, though?"
"...sure. Tha—okay, sure, whatever. Um. My mother's a sensible person who knows magic exists and knows me very well, is this Cerberus dangerous or something?" Pause. "When he's not a teddy bear."
"I don't know him that well but I'm pretty sure he's good-natured. Kinda bad at explaining things, but he is helping me with the cards. He's got a big sweet tooth so if you have cookies or anything like that they're liable to be gone. I'll just go show my homework to dad then if you wanna ride in my backpack and give me directions I can bike us over to your place."
"...in your backpack. That's delightful. But no, if Cerberus is okay I think it's best if we chase this card thing and fix it."
"Unless you're really good at sitting still or want to bet nobody notices an animate teddy bear and makes a scene out of it?"
"No, I'm cool, I'll go in your backpack, do I even need to breathe?" He checks. "Yep, I do, leave some space for air please."
"Got it." His two cards go in either side of his jacket pocket. He runs down and displays English homework and promises to have Math and Biology done today. He runs back up empties his backpack until it only contains the Clow Book, one notebook, some pencils and a calculator.
"Right, panic over, introductions. Hi, I'm Terry Miller. Please don't call me Terence unless you absolutely have to."
He holds out the backpack. When Sadde hops in he closes it only halfway, plenty of space for his head to poke out. And he heads for the garage and gets on a bike and zooms off toward the mall, taking shortcuts away from big roads here and there. It's a pretty nice bike. "I'm gonna meditate again near the mall. Won't take as long if we're closer."
"Okay." Pause. "Can I grill you on this magic after I have my body back? This looks fascinating after you get over the switching-bodies thing."
