their chairs, giving her their full attention.
“You two are more trouble than you’re worth,” says Smita. She doesn’t bother with a preamble or a salutation: both would be a waste of her time and theirs. Thawing slightly, she adds, “Thank you for coming in again. I do appreciate it.”
“It’s not a problem,” says Roger. “Though we don’t quite understand the reasons. Did something go wrong with our original samples?” Giving blood isn’t the most fun way to spend an afternoon, but blood tests require far less in the way of volume. The juice boxes are almost a formality. Which reminds him . . . “Also, where’s my juice box?”
“I am the only adult on this campus,” says Smita. She opens a small fridge, extracts a juice box, and tosses it to Roger, who catches it one-handed. “There was nothing wrong with your original samples, exactly. We had a bit of confusion when we thought we’d cross-contaminated them. I want to review a few things with you.”
“Do we have some sort of fatal disease?” asks Dodger. “If it’s sexually transmitted, only Roger has it, and I should be free to go.”
“I love you too,” says Roger, and punches the straw into his juice box. He takes a swig. Artificial grape: yum.
“You do not have a fatal disease, sexually transmitted or otherwise,” says Smita, after a pause to scowl at them. “What you have is a virtually identical antigen footprint, lacking the distinctive methylations we’d expect to find in . . . Not a single word I’ve just said made any sense to the pair of you at all, did it?”
“Nope,” says Roger amiably. He’s lying. He knows all the words, if not the ways she’s putting them together. He also knows Dodger doesn’t. It’s easier this way.
“Are we biologically related or not?” asks Dodger. She needs science to confirm the answer she already knows. Once science says it, it will become immutable fact, and right now, Smita is science. Smita holds their future in her hands.
Smita laughs. It’s a strained sound: the laughter of a woman confronted with a question that can’t be answered in any simple way. “Dodger, if you told me you were identical twins, I might be inclined to believe you.”
“We’re not identical,” says Roger. “There are certain physiological differences that have absolutely taken that off the table.”
“I’m aware,” says Smita. “And yes, when we did the DNA analysis, we found that you are, in fact, biologically different genders, and you display the markers we’d expect to find given your general appearance. You understand that a DNA test is different from ‘getting a blood test,’ yes? Blood tests can rule out relation, but a DNA test is used to rule it in. We’ve been looking at the basic building blocks of what makes the two of you so goddamn annoying. I think I may be able to isolate the gene for ‘smartass’ based on your DNA. I’ll win the Nobel Prize.”
“Remember to thank us in your acceptance speech,” says Roger, and takes another drink.
“Oh, believe me, you’ll get all the credit you deserve,” says Smita.
“We know what a DNA test is,” says Dodger. “Did we mention how grateful we are that you agreed to do this? Because we’re super-grateful. So grateful that clearly Roger can’t even put it into words, which is sort of comic, if you stop to think about it.”
Roger rolls his eyes and keeps drinking juice. For once, his input isn’t needed. It’s almost pleasant. He can just recline, wait for his blood sugar to recover, and listen to Dodger and Smita snipe at each other over someone else’s field of science. This is the sort of activity he could enjoy on a regular basis.
“He’s refreshingly silent,” says Smita. “Let’s go back to your earlier samples: I don’t think anything happened to them. Based on the results, I think they were exactly what they were supposed to be. Some of the other students who helped me with the DNA tests wanted to be sure, so we needed more blood. More blood lets us run more tests. More tests lets us figure out whether you’re actually humans, or whether you’re Martians doing a very good job of impersonating humanity. My bet’s on ‘Martians,’ in case you wondered.”
“We always assumed Midwich cuckoo,” says Roger.
“We come in peace,” adds Dodger dryly.
“I wish I could believe you,” says Smita. She leans against the counter, looking at them. Her expression is grave, but there’s interest in her eyes; she has
