There is a Light inside of everyone that if we bury we will become the antithesis of what we hate. And then we will truly become Darkness. And you get a kickass theme to boot

Dominic:*puts down the photo of his mother* Some things may end. So be my time of mourning must as well. I bid the farewell mother. But I will never forget you nor your face. Even as my mind drifts, my soul will hold that final bastion of light that is your smile. Even if I try to bury it your light will be shining inside of me. Forever.
