"If you say so. You seem pretty smart, so I think I have to trust your judgment." 

She giggles. "Such a flatterer." She plants another peck on his lips.

Kisses!

Alistair is appropriately enthusiastic. 

They can keep doing this for a while.

Eventually, though, they must return to the humdrum of daily life.

They do! And the humdrum of daily life happens to be the weekend, and although Alistair doesn't have any way to contact the cardcaptor and his friend he does go to the same school as them.

So, after a weekend of magic testing and learning, and most of a school day, Sadde ditches his last class to wait in front of Alistair's school.

The cardcaptor's friend is apparently ditching class, given the way he's sneaking back into the school when he spots Sadde.

"Shouldn't you be in class, young man?" 

Sadde realizes the boy probably won't recognize him... and decides to milk this. "I should say the same to you."

"One of us is actually supposed to be here, and it's not you. Is there a story there?"

"I'm actually an agent of a family of sorcerers scouting this school for its magical secrets."

"Good for you. Trouble is, we already have five of those. Magical secret agents really like pretending to be high schoolers."

"Drat. I should report to my shadowy masters so they can come up with a better plan."

"Here's one: find a less boring school to scout. I hear they've got three whole magical secrets the next town over."

He starts trying to climb into one of the windows.

This doesn't go well for him.

"You want some help?"

"I'm good, I didn't lose any limbs."

He scrambles to his feet.

"Nobody saw that, right?"

"Only if I count as nobody."

"Do you want to?" 

"No, that was awful, I don't even know what that means. Ignore me." 

He continues trying to break into the building he's required to be in. 

"Why exactly are you trying to do this?"

"I'm trying to sneak back into class so the stupid rich kid with his stupid superiority complex doesn't have more ammo when we meet up later. Shouldn't you be trying to sell me drugs by now?"

"Do I look like I'm pushing? And why weren't you in class anyway?"

"I felt like getting a bite to eat and not experiencing the wonders of school. Any reason besides dealing for hanging around someone else's school?"

"Yeah, I'm waiting for the bell so I can meet up with a couple of people that study here."

"...have we met?" 

"I think you'd remember me if we had!"
