They don't have to wait long, anyway.

"Hey, Stiles. Um. Ashton...?"

"Alan?"

"Hi, other person. Do I know you?" 

"Alistair," he corrects. "Good to see you all."

"So we're all studying together?" 

"We can go to my house, I have to explain what's going on to my dad, anyway." 

"I don't think that's a good idea."

"Aren't we waiting for Sadde?" 

"Hey new guy, mind introducing yourself?" 

"Hi, I'm Sadde. Why's it not a good idea?"

"We shouldn't tell more people than we have to. A lot of sorcerers want things to stay secret."

"I mean, I understand that as a general policy, but it seems prudent to have at least people immediately close to sorcerers know some."

"I don't think that's a bad philosophy, but it might be bad policy. Sorcerer clans who don't like what you're doing tend to demonstrate their dislike pretty clearly." 

"Is magic secret because it's actually rare, or because of a massive conspiracy?"

"Yes."

He shrugs. "I still think it's wise to tell him and Scott's parents, my mother knows all about it."

"Yeah, definitely with the cool sorcerer on this one." 

"Alright, I can admit when I've been outvoted."

He bows mockingly.

"Are we ready to 'study'?"

"Guess so!"

In which case Stiles drives the party to their objective. 

"My dad should be home in less than an hour, if you guys wanted to avoid him." 

"Should we?"

"You're the decent sorcerer, he'll probably like you just fine."
