Stanley "Stan" Pruitt is the older brother of Alex and Molly, and the oldest child of the Pruitts.

Home Alone 3

Like Molly and the family parrot, Stan shows disrespect to Alex at first. But later, after Stan discovered that Alex was probably in danger because of intercepting a top-secret electronic device that was stolen by a group of international criminals working for a North Korean terrorist organization, and then learned that Alex had survived and fought off the criminals all by himself, Stan was impressed. He shook Alex's hand while remarking that what he did was great.

Stan is last seen with the Pruitts, Mrs. Hess and the FBI agents when his father returns. He remarked that the computer company that got their chip boosted was giving Alex a reward, which Molly revealed was a six-figure sum of money, which she thought was "extremely cool".
