I hope the next episode will bring some definite answers, but I wouldn't count on it (I do hope we at least learn what happened to Ohsugi). Saki learned quite a few strange bits of info in any case. I'd hope that makes her and Akira closer, even if it makes her more suspicious of Akira.

I don't think we yet know if Selecao can earn money back into their Selecao accounts. Even if XI bought the hotel back, the money might have disappeared for good. In a certain sense that would make even more sense considering the game was to see who could do the most good with a definite amount of starting money. Still, managed hotels normally bring steady operational profit and that might have gone somewhere more permanent. Considering Akira is living in an empty mall, he's not the smartest person with money, though, in any case.
