" There was a lightness in Jem's chest that he realized, finally, was joy. He saw the joy mirrored in his parabatai's face. The face of the one you love is the best mirror of all. It shows you your own happiness and your own pain and it helps you to bear both, because to bear either alone is to be overwhelmed by the flood. "

― Cassandra Clare , Learn about Loss (Ghosts of the Shadow Market, #4)
