Loneliness bears down on a soul, whether there's a belief in souls or not. The feeling of immortality transcends even the simplest of human minds, but not everybody wants to live forever. And of those who do, most do not wish to be alone. How painful a thought... perhaps to die without a hand to hold, or without that one last kiss.
Knowing that one is a monster makes it difficult to foster a relationship, but even the most evil tend to find someone to fall back on when legs become too tired to stand. Love is not an emotion reserved for the good of heart. There is no black and white in feeling, only sensation. And each has a right to it.
It's been years since first meeting, a brief encounter beginning long absences separated by brief encounters. The revelation that absence often happens when in the same room was a dishearteningly valuable lesson to learn. How else do priorities objectively fall into place? Subjective existence is fraudulent, though potentially blissful. Still, it's better not to live in lies. There's no point to the sun if there's no enjoyment in sunlight.
The parallels are striking, maybe even deceptively so, but it's undeniable that they are there. Paths crossing too randomly to be random, both in choice of careers and of travels. Complicated minds succumbing to simple inclinations to believe in fateful pattern. Nature's patterns used to justify those beliefs... day and night, asleep and awake, death and life. Experience and education are powerless in the face of raw emotion.
A vision of loveliness, sitting awake in the dark. Both eyes open, out of fear as well as a strange anticipation of something new. A subtle appreciation of life overshadowed by an inexplicable desire for something else. Death is becoming, but only from an acceptance of things for what they are.
Silent steps from behind exposed shoulders. A smile sinister, yet longing. It will take time to come to terms with what's to happen, but the pain of involuntary solitude is too much. Shadow leans into neck, fangs bared. The unconventional embrace of punctured skin, the letting and drinking of blood, ensures companionship until the end of time.
Even if she hates him for it.
