Recced because: Sometimes, you just need to sink your teeth into a nice long descent into madness, and Versaphile serves that up in spades. The Master defeats the Doctor's gambit with the Archangel network, and breaks his spirit. Dissatisfied with a Doctor that won't fight back, he impregnates the Doctor to give him something new to care about. It's kind of a mobius strip of a hurt/comfort fic, and makes for a gorgeous case study of how love doesn't necessarily make you a better person, it gives you an excuse to be any kind of person you want to be. And the Doctor and the Master really do love each other in this story, that's what makes it beautiful and terrible all at once: they are crazy about each other, and they're also just plain crazy.
"I won't leave you," the Master said, knowing what the Doctor needed to hear. "I'm not leaving. I'll keep you safe."
"Master," the Doctor said, as much a plea as a sob, and oh, there was his reward, his hit of pleasure amidst the pain. "Master," he said again, and moaned softly as the Master obligingly toyed with his mind.
His body was falling apart, but oh, the Master held his mind together.
