Bruce watches her pause and calculate without looking like that's what he's doing; he has no way of knowing what she's thinking, or why. It could be any number of things, up to and including 'Is he really that much of a control freak?' (yes) and also 'Why is he even offering?' Valid questions, all.

He makes a small gesture - not an imposition. "..Someone I know from home was kind enough to let me stay with her when I first arrived. Consider it paying it forward."

There's no concrete answer for making the offer, even in his head. He wants to say it's because he's doing what he should, that Vanessza is a veritable friend. But he wonders how much of this is a desire to know more about her for strategic purposes. Should he be doing that? ... Is there a difference with him, any longer? Is he capable of separating?
