[Death by Mirrors]

Trees:

In a forest of a hundred thousand trees, no two leaves are alike. And no two journeys along the same path are alike.
― Paulo Coelho, Aleph

Love:

"Emori, you know you can correct your defects here."
"I would, if I had any."
― The 100, Red Sky At Morning

(context, if required: Emori was born with a mutation that leads her own people to cast her out and/or try to kill her. Then the moment she gets a chance to be like everyone else, she doesn't even feel the need to. Now if that's not a result of love, then I don't know what is. Doesn't even have to be romance here. Just the fact a healthy and positive self image isn't bought in the supermarket.)

Melancholy:

Dogs were generally incompatible with melancholy.
― John Connolly, A Game of Ghosts

Food:

"Don't order any of the faerie food," said Jace, looking at her over the top of his menu. "It tends to make humans a little crazy. One minute you're munching a faerie plum, the next minute you're running naked down Madison Avenue with antlers on your head. Not," he added hastily, "that this has ever happened to me."
— Cassandra Clare, City of Bones
