At the end of the Vanishing Point, Teddy shoots himself in the head and the shot shows blood spraying out of the side of his head opposite the pistol indicating the bullet went completely through. In The Passenger we see a shot of Delores removing a bullet that flattened itself against Teddy's central housing containing his core sphere that she has just removed from his head. If the bullet caused an exit wound it could not have flattened itself against the housing. See more
Now, the lesson is: if you're looking for a reckoning, a reckoning is what you'll find! If you're looking for a villain, then I'm your man! But look at yourselves.

You paid them for this land with lead, and I'll pay you back in full! You wanted me? Well, all I can say to that is: here I fucking am!
