Just a note from a newbie on the whole Driveshaft thing, according to an interview with the actor that plays Charlie, His character was supposed to be from a rock band, that was in the script, but... and this can shoot down the theory real fast... He made up the little diddy and song on the set during the filming. So unless the writers are quick to fit this in, I think its a dud theory. However, I am curious, does this effectively end the Ethan story line?
