I love this--you capture the sheer fucked-up-ness of their relationship perfectly and it so fits Starscream, especially--I mean, I'm not familiar with anything more than the basics of the Shattered Glass-verse, but it makes so much sense that Starscream would go to someone who would indulge in a little sadomasochism with him if Megatron wasn't--I mean, that's not canon, but assuming it were, and...

ARGH, I'm not making sense! But seriously, you did a fantastic job. Absolutely incredible.

I love how you give Prime these little moments of not-quite-decency, kindness--and it's all mixed up into a glorious mindfuck of the first order, on top of Starscream's need to be forced into submitting, and just--wow. Incredible!

(Dang, I'm really not managing anything like coherency, am I? But seriously: incredible. I think your fic blew out my mind.)
