Sebastian's family is Catholic. His father, Lord Marchmain, had been an Anglican, but he had converted to Roman Catholicism, his wife's religion. The family talk a lot about religion which surprises Charles, who had always thought that Christianity was not an important subject. Lady Marchmain, Sebastian's mother, is a very strict Catholic. She tries to control others by making them feel guilty. Sebastian finds comfort by drinking alcohol. He often gets drunk, and over a period of two years he has less and less to do with the Flyte family.
