Louise and William were the parents of Ty Collins. They appeared after the announcement that Adrianna Tate-Duncan had gotten pregnant by Ty. Louise, in particular, was very adamant about Adrianna giving the baby up for adoption, pulling up a contract which would have put a gag order on Adrianna from ever talking about her pregnancy or the the fact that Ty was the father.
When Louise showed up at the Tate-Duncan house to explain the terms, a surprised Constance Tate-Duncan was furious with her holier-than-thou attitude and how condescending she was being towards her daughter, so she threw her out of her house. The contract was never signed and Adrianna announced to the entire school that she was pregnant.
