Buldeo and the fellow prisoners of Yash aren't working against the alleged villain at all. So who was the top villain after all, if not the real villain like Ernie Price? His name is Frederick Andreas Gellman, which is associated with the cigarette in shortened form.
Meanwhile, Yash isn't really a Monster of his making, so he has downgraded from master to minion. Instead, protegee Andreas has become that Monster, since his father Peter Ivory Gellman was the titty king of fur maniacs, whose entourage hunted countless animals - including Bagheera's mother Madhubala the panther - for their furs and pelts.
The nasty Yash sort of lies a lot, as his real past contains his miserable days of coal mining in India, which indirectly led to his (equally misguided) parents' deaths far away. He surely is the immigrant middleman between mere strangers and the gluttony behind a magnificent exotic fashion business.
A day later, so many of the hostages, including Buldeo and the Potmas, escape the factory in a harrowing fashion. Indeed, they are all escaping from the grisly operations of Ernie Price's own making.
