““With Lincoln, the line between their two selves is blurred. She bathes him and wipes off every bodily fluid, and he sticks his fingers in her mouth or catches his balance with a hand on the top of her head. He catalogues her freckles and moles as carefully as he keeps track of his own scrapes and bruises. He does not quite know that he is a being apart from her. Not yet. For now, her arm is as accessible as his arm—her limbs are equally his limbs. They are interchangeable.””
