I don't know how you have avoided being crushed to death by infodumps. Especially considering this is all in Anne Rice's prose, which is not exactly light.

Quinn's a turd who probably thought he was too special to learn basic arithmetic, his family's obnoxious and incesty, but most of all I wonder why Anne Rice thought all this information would be good for the reader to know. It's like one of those super-long RP applications from a 13-year old who thinks their OC is the coolest ever.
