He feels an open summons and lets it grab him -
"I was murdered when I was 22, I wrecked some guy's sketchy business in the process of going public on the existence of daeva not-quite-anonymously enough and next thing I knew I was in Hell."
"I'm extremely sorry," says the summoner sincerely. Pause. "... I should worry about that. I would rather not end up dead before I can accomplish anything."
"Do not underestimate the vengefulness of people with strong economic reason to want you to fail."
"I won't," he promises. "I do not want to die at twenty-two. Or, for that matter, at fifteen."
"Right then, that is basically the useful life lesson my death can teach you. That and the thing about summoners turning into daeva."
"...heh, I wonder if Charlie's house is here." Pause. "I wonder if there is a Charlie here."
"... Ah. Do you want to right now? I can explain things to my dad while you do. Hell, I can put an invisibility spell on you if you give me like - ten minutes, if you're worried about him seeing you and you having wings. Hidden under a trenchcoat they might be."
(He is not going to intrude on Cam's time with his father. Why would that be a thing that he would do?)
"Is your dad going to be annoyed about you letting a demon run loose? I'm not in a hurry."
"Okay." Cam looks both ways, then makes a motorcycle out of nothing and hops on it and zooms down the street without a helmet.
Cam is back on the motorcycle a few minutes later and parks it in the relevant driveway.
There is a brunette, sitting outside. "Hi, shirtless trenchcoat guy. Darren has spilled the beans." She waves. "What's up? Cool motorcycle."
"Got it in one! Yup, sister. Darren is geeking out, by the way, he's like 'Eeeee maybe the medallions will actually work eeeee' and that's why I'm outside."
"Well, maybe they will. Should I go in, do you suppose? I can make arbitrary things, but ex- I mean internet access isn't one of them, at least not easily, so I should probably be slightly on the grid while I work out how what I remember matches this place."
Shrug. "Go for it. Pretty sure dad and Dare will be competing to make sure you are not left out in the metaphorical cold."
"- well honestly I've got absolutely no clue why it picked him in particular," drifts Darren's voice towards the door. "Or, for that matter, why it was not actually a working teleportation spell! I will dissect it and try to figure out what I missed."
"Okay," agrees another voice. "Be careful, please. Do I need to grab Lynn and get her to check him over? Actually, you know what, nevermind, she's probably already on her way because she is Lynn."
