Description: Gary is baby-sitting Yvonne's young nephew Arthur when he disappears. He suspects that the little boy may have wandered through the time warp back to 1942 and goes after him. Reg finds a small boy and Gary attempts to return him to the present but the child is unable to get through the portal. Of course he is not Arthur, who is found in the present and Yvonne goes off again, leaving Gary to mind him
