Sonny can pick up a few theories about Credence from what he says. My sister Modesty comes from a family of 12. Implying that, probably, they had separate families before, but that they're considered family now. That means Credence is probably adopted, or possibly in foster care or something.

Of course, they're just theories. Sonny can't know for sure, and he's not about to pry and ask, either.

"Oh, yeah," Sonny confirms, laughing. "We're Italian. I've got three sisters, both my mom and dad have siblings, and they all have kids, and some of them have kids. I've got more cousins than I can keep track of. Family get-togethers are insane."
