He shakes his head.

"Any opinion on who should have the info on how to summon me and Mrindeh back in case of you dying? Actually, Mrindeh might want to be resummoned precautionarily lest she vanish while holding a baby, I'm not sure how far she's gotten on that."

"...An undead maybe, since they're indestructible? If they can. Or Naruto, since Minato can just fetch him." Though then Naruto might try to talk to Sasuke.

"It's probably a good idea to know if the undead can, if they're okay with the risk it'll screw with their whole afterlife arrangement in some unguessable way."

"I'd have to ask."

"I'll email Tobirama, I've given him a computer."

He nods.

Want to see if you can summon daeva? Warning: may complicate your whole situation with being dead.

Someone needs to figure out if it will. I am likely the least needed of the Hokage that Sasuke will consider trustworthy, besides.

Cam writes to Mrindeh and gets a pretty quick turnaround to the effect that she is not presently holding a baby and can do more experiments. "Okay, if you dismiss Mrindeh then I can remake her circle for him."

He does so.

Cam finds Tobirama. "Hullo there."

The first one he finds is a clone, who directs him to the main body, which is reading. "Hello. You mentioned learning to summon?"

"I'm not going to put you through the whole four credit university course, but it'd be good to know if you can, yeah. Might also be good to know if clones can."

"What happens when the summoner dies?"

"Demon goes home. So probably ultimately this particular demon will want to be summoned by some minor functionary in the Snow government, or something, who is unlikely to die or experiment with dying-adjacent behavior, but she's up for experimenting."

"If we decide to resurrect my Uchiha student, it would be reasonable to keep him back at the base, to provide a back-up for resurrections and summonings."

"Not going to want to do field work and not going to be a target for anything?"

"He's done field work before but I believe isn't wedded to it. I'm unsure if anyone would target him specifically, though if someone forces Sasuke to dismiss the resurrection technique he'd be caught in that."

"I wonder if people who are themselves undead can do resurrections? Probably not a good idea even if you can since you'd have a cascade if the live person dies."

"We'll persist even if Sasuke dies. The problem is if someone mind-controls him. Still, if I were to resurrect someone, and Sasuke was forced to dismiss me, whoever I resurrected would also remain."

"And I haven't tested undead performing the resurrection technique, but I can use all other techniques I could in life."

"Anyway, to see if you can summon Mrindeh, you fill in the gap in this line." A paper circle appears and Cam offers him a pen.

He does so, calmly regarding the circle as he does.

It's written in English.

Mrindeh does not appear. Cam writes to her to see if she's just not answering for some reason. "She didn't feel the circle," he replies.

"That removes some of our options."
