What questions are answered in chapters 30-33

These are what I picked up as far as questions go,

Herbert tries to cheer Pip up, though he also tries to convince him that, even if Miss Havisham is his secret benefactor, she does not intend for him to marry Estella. Herbert confesses to Pip that he, too, is in love and, in fact, has a fiancée named Clara, but he is too poor to marry her.

When Pip meets Estella, he is again troubled by her resemblance to someone he can’t place. She treats Pip arrogantly, but sends him into ecstatic joy when she refers to their “instructions,” which makes him feel as though they are destined to be married
