In the first act of Mad Max Fury Road, the war rig is manned by The Ace (oldest guy there, kind of a captain), and a crew of warboys. The last time we see them is just before Furiosa enters the storm, and they just stand there, on top of the rig, looking at it. I think there were 3 or 4 of them. In an ideal position to take back the rig.
Also, Organic Mechanic, and Miss Giddy? Did they just disappear after Splendid's death?
What happened to them? Does Ace appear later on?
edit: Ace was knocked off the rig by Nux's ramming. What about the rest?
