“ When she opened her eyes, she was both in her body and watching it, nowhere near the cavity of the tree. The Blue that was before her stood inches from a boy in an Aglionby sweater. There was a slight stoop to his posture, and his shoulders were spattered darkly with rain. It was his fingers that Blue felt on her face. He touched her cheek with the backs of his fingers. Tears coursed down the other Blue's face. Though some strange magic, Blue could feel them on her face as well. She could feel, too, sick, rising misery she'd felt in the churchyard, the grief that felt bigger than her. The other Blue's tears seemed endless. One drop slid after another, each following an identical path down her cheeks.The boy in the Aglionby sweater leaned his forehead against Blue's. She felt the pressure of his skin against hers, and suddenly she could smell mint. It'll be okay. Gansey told the other Blue. She could tell that he was afraid. It'll be okay.Impossibly, Blue realized that this other Blue was crying because she loved Gansey. And that the reason Gansey touched her like that, his fingers so careful with her, was because he knew that her kiss could kill him. She could feel how badly the other Blue wanted to kiss him, even as she dreaded it. Though she couldn't understand why, her real, present day memories in the tree cavity were clouded with other false memories of their lips nearly touching, a life this other Blue had already lived.Okay, I'm ready- Gansey's voice caught, just a little. Blue, kiss me. ”
