Who's putting out unfriendly specific summons for him?

Lecturey crochet lady, somebody in Antarctica's research base, and a cult in Canada.

Are the latter two designed in such a way that if he mastered a nonverbal Accio he could cast it -

Antarctica's prevents that in practice on the grounds of affecting things outside his circle; the cult's is handwritten and probably allows it.

Can't risk it, then. Darn. He takes randoms until there're new ones.

Dwarves, Godspring, Dwarves, Mars, orcs, Earth, Earth, Dwarves... Antarctica circle is gone now.

He writes Timothy a note and he makes himself two hundred flashcards with words and phrases he might want to say and then he takes a specific summons.

Lecturey lady! He is again gagged and lectured (this time about being a bad influence on depressed teenagers who just need sunshine and chocolate and somebody to talk to) and then given a book of glass art and told again to make something nice for his little girlfriend so she's not jealous of that pretty angel, now, hm.

He uses the cards to spell 'thank you'. 

"You're welcome, young man, run along now," and he's dismissed.

Next one?

TV show. Does he want a recurring role in Sesame Street Luna, they like his camera presence.

"I'd love to, but the GCP recently outlawed telling the truth about ex-summoners becoming daeva and sent me letters threatening to arrest me for it, so I can't commit to taking recurring summons. I'm sorry. I can send you stuff remotely if you want occasional cameos."

"They... why'd they do that? I summoned my granddad and there he was just fine."

"I have no idea! Lots of people have summoned their relatives, lots of people know it's true, they're not going to be able to keep it a secret forever. But - it's kind of weird that it's been a secret this long in the first place. Maybe they wanted it to stay one, for some reason? Anyway, they didn't tell me a reason, they just told me that there was a law against it now and unless I took down all my videos immediately they'd arrest me. It was weird. - I didn't take the videos down. People deserve to know. Aren't you glad you got to see your granddad?"

"He was a sourpuss, actually, but I knew he summoned some folks."

Giggle. "Okay. There's an afterlife for everyone else, too, just no way to reach it."

"Granddad mentioned that. Pity they can't be summoned."

"The Elves are working on some kind of plan with all their fancy dimensional portal tech."

"Oh, good! Are you going to post about that?"

"Sure am! I try to not do politics stuff every single video and I want to say something about the demon who got arrested for helping someone daevafy, but I'll probably do a video about it this week or next."

"Cool. Email me if you have a chance to take a role."

"Thanks."

"No problem! Good luck out there!"

"Thanks!" 

And another one -
