Unfortunately for Hawkeye, Leon is what some in the business call an oblivious motherfucker. As such he just laughs it off, catching some of the intent but assuming it's just a joke with no genuine flirtation behind it. You know, like very heterosexual men do to each other, especially in the military.

"D'you regularly get yourself into trouble while in drag?" he asks, eyebrows raised in mock surprise. "Or are we planning on recruiting a third for some kind of elaborate training drill here?"
