Monday evening, Jarvis inquires of Cam, "Sherlock would like to know if you would be interested in duplicating some books on magic for us, and what information about the books you would require in order to do so. He has been feeling restless and I believe he intends to go shopping."
Cam continues figuring out how to word his email to the NIH. It's probably not going to come to anything, but if he tries enough similar organizations maybe something will stick. Once he gets out of this house he's just going to fly to Africa and deploy massive clouds of sterile male mosquitoes on his own recognizance, though, that worked great in 2044 and it should work just as well here and now. After he's got to a good stopping place in his draft, a few hours after Sherlock's departure, he meanders to the kitchen for a regularly scheduled food-appearing.
Cam goes back up to his room without making any groceries and fetches his computer, folds his wings up snug, puts on a heavy leather trenchcoat to cover them up, and goes down to the garage. "Unless you think Tony will begrudge the garage space, gonna make a motorcycle."
"I expect him to joke that you may only store your motorcycle here if it is sufficiently awesome, but not to actually complain regardless. Also, it may be relevant that Sunnydale High is built on top of a Hellmouth - the site of a currently dormant gateway to a hell dimension. It is the reason why Sunnydale is such an epicenter of magical and demonic activity, but most of the time its exact physical location makes very little difference. I don't expect it to have anything to do with why Sherlock is late, but I can't rule it out."
"Uh, okay, will typical demonic activity be scared off from bothering me if I show off the wings and maybe sprout horns and fangs and surround myself with fireworks?" Cam asks, beginning to make his motorcycle. It is dark blue with white Milky Way patterns spangled across it.
