Woah! I read the story title, laughed a little at the memory of a great song... And then got a fic far darker than I'd imagined!
Wow. This piece is beautifully well crafted. You can really see Lex's narcissistic tendencies coming out to play. It also puts his actions into a better light. Because he does move too fast but the way you've painted it, he's not only aware it's too fast, but it's strategic. Bone chillingly good.
