Well Scott's adopted parents did lie and told Lilly and Rufus that he died in a boating accident so that they would stop looking for their son. Scott is Serena, Dan, Jenny, and Eric's half brother. He really just showed up so that he could meet the family. He met Lilly and Rufus as well and they told him he is always welcome to come back and visit. He went back home to the parents who adopted him In Boston and just never came back on the show so far as i know of i have no seen season 5 yet.
