What happens to the people that Sam leaps into?
As mentioned above, when Sam quantum leaps into someone, they take his place in space-time. That means they end up at Project Quantum Leap in the future. For security purposes, these people are detained in a large chamber called “The Waiting Room.” The Waiting Room is almost entirely blue and has only one known exit that is locked electronically. The only piece of furniture we see in the Waiting Room during the series is a table with a mirrored surface by which the leapees can see Dr. Beckett’s reflection and witness firsthand what has happened to them.
