Who outbid Tiana for the restaurant?
It's strange that after being derelict for so long, someone would walk in and outbid Tiana just when she got enough money for the down payment. Given Beaufort's reaction to Tiana saying that she finally had enough for the down payment, he'd be a logical person to try to thwart her dream. But, I assume he's just a cook (he's not called Duke, after all, and it's Duke's restaurant -- he's just the short-order cook) so how would he come up with the money? Doctor Facilier would be another possibility, but when the Fenner brothers tell Tiana she's been overbid, Tiana isn't a factor in Facilier's plot against Big Daddy. Presumably the Fenners were just brokers, and willing to sell if Tiana had the money, or they would have rebuffed her from the start.
So, who?
