Killian Jones and Emma Swan are both part of the same drug house. The two never thought that they would find someone who could listen and understand their thoughts and pain. The suffering they've both been through is enough to last several lifetimes, but for these two unfortunate souls, it was all crammed into two teenagers who knew not of what they had done to deserve it.
Killian, addicted to Cocaine, and Emma addicted to Heroine, share pain and suffering with each other. And they might not know it, but the longer they're taking, injecting, and snorting those things that destroy and tare them apart from the inside, is the sooner they will fall apart and lose hope.
