Explain what you learned in this chapter about cole's parent?

Cole explains to Garvey in this flashback scene how much he resents his parents, especially after their divorce. He reveals how they drink a lot and feel that nothing he does is good enough for them. When his father drinks, he hits Cole repeatedly and abuses him in a drunken rage. Back on the island, the fire is burning as brightly as ever, and Cole decides to swim to nearby islands in search of others who can give him a ride out of this wilderness.
