after shelley, dana and faith graduated, three new girls (andrea "andy" cord; jane barrett and october "toby" houston) moved into 407, and on occasion, the six girls would get together, mainly for their former housemother's wedding and her pregnancy. jane's family (the barretts) had helped give the money to build the school's science hall named barrett hall. after alison's marriage and her move to boston, a new housemother named meredith pembroke comes along, and at first, handed out demerits with reckless abandon because she was overreacting to her own wild adolescence. andrea, jane and toby talked her through the rough time, and then meredith (nicknamed, merrie) became as nice and friendly as alison had been.
