Lenny scrambled to explain himself by talking about things like it being "too good of an opportunity to pass up" and how "the market for children is better than ever." Will didn't buy a single word of it.
Their business was booming without needing to dabble in human trafficking. Did everyone forget that they stopped doing that because it was how Alfonzo ended up dead in a shoot-out with the cops?
Will had always hated that part of the business anyway. Maybe it was because he was first exposed to it when he was a child himself. Or maybe it was because too many of those little girls looked like Hazel. The demand for blonde blue-eyed females was especially high.
After living with Charlie as long as he had, he had no illusions about what humanity was truly like. Illegal adoptions didn't even comprise one tenth of what happened to trafficked children. Typically, buyers had much more sinister motives.
