If your cracker ass can remember hundreds of pokemon names for the duration of a game, you can remember a dozen russian names for the duration of a book

Best part of this is that Russians have three names (a first name, surname, and a patronymic) and they love using nicknames. So the main character is Rodion (first name) Romanovitch (patronymic) Raskolnikov (surname), but can (and is) called by any of those three names. He’s also got nicknames like Rodya, Rodenka, and Rodka. So this deranged individual (who decided to call Raskolnikov “Pete” I guess) is going to be hopelessly confused when somebody starts referring to Rodya, and he’ll think the book is filled with like five times as many characters as it actually is.
