I am not a big fan of Fyodor, he's probably my least favorite character. It is very hard to understand where he is coming from and why he does the things he does. I find it strange that he could completely forget about his sons, or at least act like he did. Gregory is my favorite because he is one of the only responsible adults mentioned so far. I respect him for taking care of the boys even though he was not being paid extra for it. Adelaida left her son Dmitry with Fyodor and she knew him well enough to know that he would not take care of him.
