There's something about this story that pushes my buttons and makes me smile while wanting to cry. I love the final lines, and I love how you explain the taboo without going into great detail. Because, when you think about how strict certain continuities were with what was and was not forbidden, the idea of two souls becomming one really does seem like a thing that would be forbidden. I like the way you imply the relaition that Jazz and Prowl have without ever falling into 'flashback' or such and the like. Brothers? Lovers? Friends? It's never really out right stated or shown which it was and I think I like that best.
