He feels an open summons and lets it grab him -
"Sorry," repeats Cam. "Could start with the moon, if you'd rather, although the moon won't hold atmosphere so I'm not planning to actually terraform it."
"Sure. I will need a place to take off from in a shuttle about twice the size of one of those intensely vintage cars to get anything to the moon."
"In the meantime, I don't think the situation is quite as urgent as Sherlock makes it out to be. I am reasonably well-defended."
"I don't have an opinion on how well-defended you are, since I am a newcomer to this situation," says Cam.
"I'll spare you another round of the argument, then. Suffice to say I don't like to take chances."
Cam holds up his hands in a not touching it gesture. "Okay, next order of business is what?"
"Is you do what you like and I go introduce myself to the other one," says Sherlock. "Tony neglected to mention me because he didn't feel up to the task of explaining, but much in the same way that you can factor him in whenever you need something bought or invented, you can factor me in whenever you need something analyzed or found out. I believe you have an inkling of what I mean."
"Informed name-picking, huh? Well, I checked the internet for versions of my parents, both of whom were public employees in the United States when they were alive where I'm from, but no such luck - you have Martin Luther King Jr. and George Washington and Queen Elizabeth the Second but you don't seem to match up on minutiae - but if there is a me I would very much like to locate him."
"That sounds interesting. I'll want more data later, but for now—" he makes a gesture balanced neatly between a beckon and a wave, and heads for the elevator.
"Sure," says Adana, looking up from her reading of medical science in the 2000's. "Is he coming here, or should I head off to a - place or something?"
"Hello," he says. "I am Sherlock Holmes, Tony's clone. Before you ask, the technology isn't widespread; he invented it the once, when he was twelve, and has since forgotten how."
Adana blinks. Then she decides that she is not going to touch that. "Okay then. Hi, I'm Adana Sanders, I'm an angel. I'm guessing Jarvis told you the story already?"
"You may assume I know everything." He smiles slightly. "At least about what happened between your arrival and your entering this room."
She snickers, a little. "All right. Uh - I am willing to use angel powers in just about any helpful fashion. Except probably 'make me some uranium' or something, because ethics. So if you have been secretly dreaming of turning your hair lime green, I can help."
"Thank you, I'll pass. If you have any mysteries you need solved, I invite you to direct them to me."
