Re: Stuff you like to believe happened in Nolan's series
I would have loved to see Coleman Reese being used in TDKR with the scenario of Wayne losing his money because that's what Reese's job was pretty much about in TDK....keep Bruce rich(in simple terms), so him being an ally and trying to find out how Bane did what he did and then having Bane kill him would've added some closure and some development to Reese from a guy who wanted to reveal the identity of the Batman to someone who became an ally.
But...as for things I would want to believe what happened in the series?
1.) Joker went into a coma-like state sometime during those eight years after finding out Batman went into exile and then wakes up soon after Blake becomes the new Batman.
2.) Blake's first mission as a FULLY-TRAINED Batman is capturing Scarecrow and he succeeds.
3.) Gordon retires and finally makes peace with his wife while Ellen Yindel becomes the new police commissioner.
