Snape and Nygma get ready to duel
You know how Mr Alan Ituriel joked about being Black Hat's dad. Okay, what if that were true, and Mr Ituriel was his dad and raised him since he was a barely sentient eldritch squid baby monster thing. How's that possible if BH is probably really fucking old. Easy Mr Ituriel would be some immortal that one day was like"yep, I'm going to raise this demon. Sounds fun." But he's the most suburban of dads ever, but never tried stifling BH's evil tendencies, he encouraged them even.
