Cam is dipping a grilled cheese sandwich into a bowl of tomato soup when he feels the summons. He goes ahead and grabs it. Doesn't even drop the sandwich.
"It's whatever you like, but I'm having apple fritters and Canadian bacon and fancy coffee." Sip.
"Unfortunately, most things can't be cured quite that straightforwardly. You aren't having bee problems yet, those I could also fix via the 'create huge numbers of insects' method. I have interesting drugs and gadgets but they would need to be distributed by doctors or at least someone with a legal identity, and I'm only one person. You don't happen to have contacts at the NIH or anything similarly acronymical and medical, do you?"
"I have noticed that. Maybe you can tell me who to go wow and I can see if that works. One thing I can do that I cannot teach humans how to do is heal amputees, which would be suitably dramatic to get me all kinds of scientific attention but requires an amputee willing to let me saw off their stump so I have a clean end to work from..."
"I mean, slightly more cleanly than sawing and I could numb you completely but the show-off-ness would be slightly dented by the part where you don't have a documented history of missing a finger. ...Say, is the Randi Prize a thing here?"
"Doing anything along the lines of 'stopping the bleeding' will tend to make it harder for me to attach a new finger that doesn't have a layer of blood clot in the middle of it, it's really pretty inconvenient, I'd rather just talk to the NIH, I was speculating idly about how to get people to believe that I have awesome cures and treatments to share if I can't get a hearing in some more civilized way what with lacking a legal existence. By the way, after we eat I want to borrow your internet again, look for my parents, see if I can pretend to be my twelve-year-old self to people who aren't paying attention or something."
"Oh, you didn't do that last night? Sure. Also, it's not like I'm not used to periodically losing blood, I'm sleeping with a vampire. My thought would be that once it's been established that you can replace bits, a professor would be better than me at getting you in contact with the NIH and/or amputees."
"You haven't seen me replace bits. I could show a professor other things I can make and they might be as convinced as you."
Breakfast is yummy. The Internet turns up no public information about either of Cam's parents in the places they are meant to be. Professor Marsh?
Cam entertains himself with his computer during the interim. "Hello!" he says, when they have professorial attention.
"This is a matter-conjuring demon from another dimension. He wants you to introduce him to someone from a government medical agency, or introduce him to someone who can introduce him etcetera, so he can make new limbs for amputees. Real limbs, not prosthetic ones."
"Ah," the professor says. "I expect a demonstration is called for?"
"The limbs for amputees doesn't scale I only mentioned it because it was flashy I'd have to do it personally every time the real winners in my arsenal are the vaccines and fancy medical scanners and drugs," says Cam in a long sigh.
