Sebastian's mother, concerned about his increasing alcoholism, cancels his allowance. During a visit to Brideshead, Ryder gives Sebastian money, which he uses to buy alcohol. Later that day, at a party given by the family, Charles is shocked when Lady Marchmain announces that the celebration is in honour of Julia's engagement to Canadian businessman Rex Mottram. Sebastian arrives at the party late and improperly dressed. After an embarrassing scene, Sebastian flees the party, and Lady Marchmain privately dresses down Charles because he gave Sebastian money, and tells him that he is no longer welcome at Brideshead. Sebastian flees to Morocco.
