"Congratulations."

"Is having a British accent a clone thing, I wonder."

"I can't imagine how you'd expect that to be true," he says. "I grew up in London. When I'm mimicking my brother," he adopts Miles's Barrayaran accent, "I sound like this."

"I have no explanation for why it would be a pattern, but it's two for two, and Sherlock didn't grow up in London, he grew up with an AI who spoke in a British accent and picked up that accent instead of Tony's."

"Sherlock," says Mark. He feels the way Miles feels looking at him.

"That's... his name. What, do you know someone named Sherlock in addition to having a sister-in-law who is apparently the shinier version of me?"

"And, to clarify, does he have this name by coincidence or was it a deliberate reference on someone's part? If so, whose?"

"Oh, his own, he adopted the character when Tony neglected to supply him with a name."

"Right," says Mark. "See, I didn't grow up Mark. I grew up Miles - called by his name and made to study every available datum on his life. It inspired a certain kinship, the first time I read those stories - the process of extrapolating from limited information was very familiar to me. I even snuck out to the museum once."

"Do I."

"On and off," she repeats. "It's not just the accent, though."

"I wasn't getting the impression that it was just the accent," he says. "What else is it, specifically?"

"Phrasing, sort of - attitude."

"How curious..."

"Yeah. You don't look anything like him, though, he's yea high, brown eyes, not the same face."

"I don't seem to be a clone of the same person," he says, "so that's reasonable."

"Suppose. So you sound like my boyfriend and I look like your sister-in-law and this doesn't look like my math classroom, that's several mysteries."

"And I guess I'm the local expert on mysteries. Explanations, then, for why we are both here instead of the places and times we intended."

"Where are you getting 'times'?"

"You did not buy those clothes in the thirtieth century."

"Oh, there's a whole industry. I'm comparatively lucky. Some of us are grown to receive brain transplants from the old, rich, and unscrupulous."

"Thaaaaaat makes my staking hand itch."

"Staking?"
