Tell me you skip through the dialogue without reading it without telling me you skip through the dialogue.

Eulogy is the name of the slaver leader, IIRC. It's been ages since I've played it. So the guard out front gives you the four targets, tells you to get one and you can come in. I think the first four targets, even after the first one and you've gained access, are through this guard. I think Eulogy or whatever his name is just talks to you in his penthouse, which is where the aforementioned Bobblehead is. Once you're in, you can do a couple other quests. But once you've done the four slave acquisitions, the leader tells you about a discerning client who wants young females. He doesn't spell it out for you but you can pretty much guess.

Why would you think some rich bastard would hire slavers to acquire small girls? They aren't old enough to breed, and older children of either gender would be better suited to manual labor (or, you know, adults). Children require emotional and financial support. Why would he want a bunch of random small girls around? Do you actually have a theory or are you just defending pedophiles with FUD?

The slaver is a man, so assault is implied.
