Dreams - S1.E9

When Ian, Gabe, and Suki have dreams about a mysterious yellow elevator, they search for it in the tunnels. They observe a new student being brought out of the elevator. He becomes Ian and Gabe's new roommate and can infiltrate dreams. They discover Cornelius Tower's office (Tower Prep's founder) and investigate. They take some items from Cornelius' office and bring it to the observatory. Conner then escapes and reveals, in Ian's dream, that he is a "scout". They find that Conner took the things from the observatory, but left a picture of Cornelious Tower with a young child. Ian realizes that the young boy is himself.
