Piano Man
So Sam is being sent around time to put right what once went wrong (by God or something).
But in this episode, he arrives in the body of a lounge piano player who is in the witness protection programme and who originally died moments later in a car explosion.
But a guy asks to borrow his car to take his girlfriend home... and they up dying instead.
So those two people dying (who didn't originally die)... that somehow contibuted to putting things right? Huh?
