Perdus dans L'Espace s01e15
Titre original : Return from Outer Space
Lost in Space's only Christmas program. Will uses an alien transporter to send himself back to earth. However, many people believe the Robinson family to be dead after hearing the ship went off course. Nobody on Earth believes him, and they lock him up with the intention of sending him to a boys' home.
Will escapes the family home he's in, and wanders around these clueless bunch of townspeople, but finds carbon tetrachoride - needed for the food processors on the Jupiter. Eventually he convinces another boy Davey to let him out, and let him return to the planet he came from. He returns to Priplanis with this bottle. Of course no one believes his adventures until he produces the bottle, plainly labeled as coming from earth.
