Like something in Sue's phrasing amused him, Tony pursed his lips against a smile, just letting them twitch into a smirk. 'Fair enough' didn't exactly sound like she was getting what she hoped to find in Tony to help her feel needed, but the flirting and maybe a few seeds of stimulating fantasy planted was as close to what he was once so reliably accommodating about that she was going to get. There was, after all, a conflict of interest to worry about anymore-- or, at least, as far as he could tell. The details were still hazy. Still, it was a shame she didn't volley the flirting back, it wasn't like that wasn't an entirely safe playing field. Maybe it wasn't at all what she was looking for. Tony was almost forced to consider the broad spectrum of ways other people found validation outside of sex, but safety was always close at hand with an available bar to draw his attention. One second his suppressed smile, the next he was drifting towards a bottle of whiskey to pour a measure for each of them.
Without waiting for her approval, a glass was deposited in Sue's hand, and Tony was toasting their arrangement: "To expanding our horizons." Just a warm tinge coated the bottom of his glass anymore when it was lowered from his lips, and his attention that never seemed to leave Sue was suddenly flitting; to his desk, then the door, then back to Sue again only briefly. As much as he loved being the shoulder to cry on, it was a downright horrible position to be in when he wasn't allowed the reciprocal intimacy that contractually followed. Besides, he had the rest of that bottle that he'd much rather examine his own views of self-worth with.
