In 1978, Luke Spencer came to Port Charles at the request of his sister, Bobbie, who needed his help separating the object of her affection, law student Scotty Baldwin, from his girlfriend, Laura Webber.

After Laura married Scotty in 1979, she and Luke became friends while she worked for him at the mob-run Campus Disco.
