Why do I get the feeling that Cait's child abduction case is connected to Vi's past?

For all who have not read all the new lore, you'd rather catch up before jumping into here, but here's the short version: one of Cait's earliest cases revolved around a series of child abductions by a crazy chem baron, potentially Singed, given that he "has gone insane from his own cocotions". The thing is: why would someone kidnap a large number of children?

While slave-trade and child-slavery is surely a thing in some parts this world, it definetly is not a thing in Piltover and Zaun. And I doubt that it was for the simple pleasure of some really sick perversions. That would have been described as downright disgusting and sick, but not as insane.

So there is only one explanations: the weird chem baron needed the kids for his experiments. One cannot be sure what he was researching. Maybe the effects of his drugs during the growth period? Trying to slow the ageing process in an attempt find immortality? The ability to brainwash someone chemically? "Über-Doping" to ensure superhuman strenght and mind-power? Possible side effects? (Such as Pink or Blue hair...). We can't be sure about that.

And at the same time Vi is an orphan, once said to have been at an orphanage that now no longer exists and someone said he once found her in something that looked like laboratoy wreckage. Both might be true. I mean, if that chem baron was trying to get kids, he would first and before all get them from somewhere where no one would call the police or would miss them too much to the point the police became involved. An run-down orphanage in Zaun seems to be the perfect place here. However, the chem-baron's experiments required more test subjects, and as rumors spread the "ressources" were getting harder to get, so he had to move up to the somewhat higher levels of Zaun, which finally got the police involved.

Would explain why Vi is suddenly working together with Caitlyn now. After the "job-gone-wrong" at the mine she had suddenly gone missing, probably trying to find some clues about her past again, and Cait was on the same case and provided her informations and must have helped her out by, like, a LOT. Because seriously, there is no way Vi would take orders from anyone who has not earned her total respect through their deeds.

The only question is now: is this story arc long over? Or will we get to it again when it comes to the Singed lore, which we might potentially get soon. There is a Zaun event coming after all...
