But at the same time, Natasha is no idiot, and she obviously gets the point that Maria is being hunted by Osborn - who she knows is an asshole. Therefore, even if Maria does look frantic and dishevelled, she still knows Maria's come from Tony and wouldn't be such a moron in obstructing Hill and wasting time.
As for the 'cloud of trouble' following Maria - She's already associated with Bucky, who isn't Osborn's best friend, either. For Natasha to even have a public apartment seems a touch ridiculous, to me.
It's just Fraction dragging things out for another few pages so he can revisit the plot next month.
