"Fair. I really want the not-sleeping thing. Bar, can I have some breakfast?"

Blackberry oatcakes and bacon and poached eggs and apple juice!

Tasty! He does not enquire as to whether the bacon comes from pigs; it is not looking like he's going to have to deal with Revelation for a while. 

Then he reads over the legalese on one of the discarded binding circles.

- things that take effect outside the circle excepting the following: -

- upon agreement, the demon shall not intentionally at any time misrepresent themselves by word, implication, or insinuation as having completed the task -

- shall seek redress first by inquiry; failing which attempt to produce a clear attempt at dispensing payment shall -

So even if Cam had friends who could have covered for him, given him something other than a comprehensive body of works confirming Cam's story, this particular binding wouldn't have permitted that. 

He rolls it up and puts it away and composes letters to a few people at St. Mungos.

Cam goes and puts ten days' worth of chips through the read-write process and fills up his bag.

And then comes downstairs and asks if it's time to open the door to Arda.

"Yep, think so, I have messages for everybody. You okay?"

"I've been trying not to let myself get too used to 'not resurrecting people around the clock' but I'm not sure I quite managed."

"We aren't in a hurry, if that's a problem that'll get better instead of worse with a couple more days..."

"Probably wouldn't help."

"Do you want Ister working too - speed it up a bit -"

"It's not a good idea to spread around that this is doable by demons."

"Claiming it's doable from a chip is fine, right-"

"Yes but a black hole would not leave intact chips. If anyone asks it's based on Silmaril backups."

"Good to know. Okay. Good luck. Who's holding the door?"

"I'll ask Larya. She can trade with someone if she gets tired."

Nod. "Do you know how my Elf mom is best found?"

"Ríewen was on shift then and may know. Failing that osanwë."

"Okay. See you soon."

Cam nods and opens the door and interpolates a new hole in the wall and calls over his helpers.

Who accept an explanation with only a little bit of hesitation and some glances at Timothy.

And Cam installs Larya at the door and goes back to reembodying Elves.

And he ventures off to find his Elf mother.

She can, in fact, recommend some therapists. They round everyone up and return to Milliways three days later. 

And two days after that there's a letter for Cam from Maitimo with a list of people with skillsets relevant to helping with interdimensional travel or 1800 Earth who have consented to be forked. It's a sizable list; most of the Fëanorians are on it.

Cam finishes reembodying his bagful of prepped chips and then he waits for Timothy to be handy and forks the named Elves.

 " - huh. I was trying to imagine it and coming up short. It's nice to meet you!"
