I'm still not entirely sure if that means Mafia or just no time... Cho has tried to cover up her inactivity by saying that she is a bit put off, I guess would be the right phrase for it, by the fact that when she finally does arrive there are at least 3 pages to catch up on...

Edit: I'm not entirely certain how suspicious it is to be looking at all possibilities, but I suppose it could look that way. It doesn't seem like many people would actually look at all of the possibilities in depth...

Because then no one would win, of course!
