"I'm open to other suggestions, but this guy knows how to summon daeva and is not about to be very kindly disposed towards us."
"I ran out of ideas at dismissing and re-binding her."
"That could still work. She could surveil him without so much awkwardness about his personal life. We keep a close eye on him for now, and - you got married, right? I will assume here that you didn't pick somebody random without redeeming qualities. We mail your wife instructions on how to summon me. The fairy is informed that if she, or any other summon belonging to her king or people he teaches, produces a daeva who causes trouble, even if they manage to kill you, I show up and start bumping summoners off. Once this is set up we can leave them more to their own devices, and then we're at least set up for damage control if anything smaller-scale than 'wrecking most of Europe' happens?"
And probably tell more people as well. Summoning itself may be secret, but there are any number of people I'd trust with 'if I die, draw this on the floor.'
What if our Irish friends do the same? Everyone starts killing anyone who might be a summoner?"
"Our Irish friends know way less about summoning - for now, anyway, I suppose they could get lucky and find someone who knows as much as I do or is willing to go fetch a book on it and translate - you know what we could do that doesn't involve killing him that'd neutralize his summoning capabilities is keep this guy in space in zero-gravity. No floor to draw on, no summons. Not exactly pleasant, and if we left him his fairy friend she could haul them to the planet lickety-split..."
If they spread around even that one diagram, and want revenge, I'm quite confident in a clever mover's ability to wreak havoc while staying close to a summoner."
"What are you whispering about?" the mover asks. "You're not forgetting about the capsule, are you?"
"The capsule's intact," says Cam. "We're talking about how to make sure you two don't make mischief. Any bright ideas?"
"All you want is a - a non-aggression pact, right?"
But those we can enforce with daeva. The mischief we're worrying about involves summons."
"I only know the one circle." Muirchertach didn't hear the last time this came up. "I already can't summon and bind anyone else."
"That you have persisted in this state of mediocre education this long is already kind of miraculous," says Cam.
"No, but - well, I'm disinclined to make suggestions. Options for making very sure that you can't summon anybody else and wreak havoc, or teach other people to do it efficaciously, include lots of things that would be unpleasant for you in various ways. But maybe we can just operate in good faith."
"Since my head is still attached to my body, there's obviously something you want me to do. If that just means not trying any dangerous summons, I was already going to do that."
"It's been years. Is there anything I could possibly have done to be more trustworthy with what I can do, or is this all solely because I'm a summoner?"
"Well - yes," murmurs the fairy.
"But more inclined to trust me" Muirchertach interrupts. "I'm hardly going to be less careful about it after finding that out, am I?"
"I can't end the world!" exclaims the fairy. "That's a demon thing."
"Also, they're called makers now. It's more accurate."
"This hardly seems like the time to be policing my language," says the fairy, snuggling her king.
The king addresses Hank, still assuming he's the only important one. "You're clearly not going to kill me. So what are we waiting for? Fix this poison and let us go."
"Well, if that happens, there's nothing stopping you from instantly killing me. We haven't told anyone how to resummon Cam if I die so he can wreak vengeance on whoever killed me yet."
To Cam: "We might have to make two trips so she doesn't get a chance to unsummon you by force."
They are too busy cuddling to answer. That's probably a no.
"The capsule will last?" insists the fairy.
"Yeah, you're good for as long as it will take," Cam tells her.
Fairy and king float out of the ship onto the island.
"Of course, by 'Catraeth' I meant 'Camelot,' but saying that would have been almost as bad as reminding you about the camera while they were listening. Can you fly east until we're out of sight, for the same reason?"
