"Doctor, I'm not going anywhere until you explain."
(And I'm gonna guess you haven't figured it out, so I can explain if you haven't)
???: "Miss Linh, listen to me very carefully. I'm not-quite sure how to explain this...you don't remember anything before your operation, correct? Did your adoptive parents ever tell you anything about your childhood? Your background?"
"...N-No..."
???: "Then you truly don't know anything about where you're from other than the things on your ID chip-"
"What's your point!?"
???: "...Miss Linh...I have deduced from your blood samples, that you are, in fact, Lunar."
"What....h-how........I don't even have magic!!!"
???: "Yes, well...not all Lunars are born with the gift. They're called shells..."
"I'm not Lunar. I'm cyborg."
???: "Lunars can be cyborgs as easily as humans. It's rare of course, but being Lunar and cyborg are not mutually exclusive. It isn't altogether surprising that you were brought here. Since the instatement of the non-gifted infanticide under Queen Channary, many Lunar parents have attempted to rescue their shell children by bringing them to Earth. Of course, most of them die and are executed for the attempt, but still...I believe this was the case with you."
The little orange light flickered in the corner of her vision
"You're lying."
???: "I am not lying, Miss Linh."
She wanted to argue, but-she didn't know which part he had said to trigger the lie detector....
(Oh thank youuuuuu-again, can't take credit cuz this be a book but I am vibinnnnnnnnnn-)
???: "This also explains your immunity. In fact, when you defeated the pathogens yesterday, your being Lunar was the first possibility to cross my mind, but I didn't want to say anything until I'd confirmed it.
"What does this have to do with immunity...?"
???: "Lunars are immune to the disease, of course."
"No, not of course!! This is not common knowledge!!!"
???: "Oh. Well, it is common sense when you know the history....which, most people don't."
???: "You see...Lunars are the original carrier hosts for Letumosis. Their migrations to the rural areas of Earth under the reign of Queen Channary brought the disease into contact with humans for the first time."
"I thought I wasn't contagious..."
???: "You aren't now, because your body has developed means of ridding itself of the disease."
"No-y-you're wrong...I-I can't be-"
???: "I know this is a lot. But you CAN'T be here when Her Majesty arrives. It's far too dangerous-"
"N-No-I-I am not one of them!!"
