Oh I forgot about the ending, heh. On the hand it was shocking since we know Ben doesn't die... on the other hand it's a cheap fake-out because we KNOW Young Ben doesn't get killed there so it's just there to end the episode on. The time travel rules have been established, "Whatever Happened, Happened", Ben can't die in 1977.
This is true, we know it has been established what the rules are, so killing Ben is kind of cheap here, we know he won't die.
However, a thought just occurred to me, what if it is the gun shot here that causes older Ben in the future to develop that spine problem that Jack had to fix.
