Well it is pretty high proof; Tony and Bruce made it special for Steve.

Tony's own drink is forgotten for a while, as he works his way through the file. It's. Bad. And the little wrinkle of concentration between his eyes from reading handwritten Russian slowly morphs into a frown line, until he has to put the file down, and knock back the rest of his drink in one go. And then pour himself another, fuck.

He knocks the second drink back, and runs a hand through his hair, before turning the page. It's horrible, and fascinating, all at the same time.
