“If your twin was dead, were you still a twin?”

“There’s this anomaly that happens sometimes with twins. It occurs in the womb when the fetuses are growing too closely to each other. The stronger twin develops normally, while the weaker twin crumples and is encased by the body of the stronger twin, where it becomes a parasite. The result is a single child, plagued by a twin-shaped fossil inside. Like a tumor.In death Rose became Linden’s parasitic twin. They were two separate organisms once, growing steadily beside each other. Two pulses. Two brains. But she has crumpled and died, and still he carries her inside himself. She goes where he goes, feeling nothing, seeing nothing, a shadow behind his ribs.”

“When in the down I sink my head,Sleep, Death's twin-brother, times my breath;Sleep, Death's twin-brother, knows not Death,Nor can I dream of thee as dead:”

“Oy, ice-boy,” the real Puck called, still fighting his two doppelgängers. “Quit playing around with my evil twin—you have your own!”

“I thought you said he was your twin?”“Under that hair and beard, he is.”

“Sufficient unto the day is one baby. As long as you are in your right mind don't you ever pray for twins. Twins amount to a permanent riot; and there ain't any real difference between triplets and a insurrection.- The Babies speech 1879”
