Really not a whole lot to annotate this time out--to the point where this issue feels like nearly pure time-marking. Nonetheless! Ever onward!
"The things I don't could fill a book": is the Crime Bible a book of unbelief? (I'd still like to see the theology here disentangled and explained a bit more.)
"No God who would allow this to happen": the old omnipotence problem. And Cain being "condemned to an immortality of agony": first of all, the Genesis 4 business was just about Cain being protected via threat from anyone killing him, and second, if he really was masquerading as Vandal Savage all this time (without a visible mark), he sure didn't seem to be complaining about long life.
White guy forcing black guy to call him "master" loses some of its impact when the latter is now a chalky-white husk without the black guy attached to him. (And it appears that the story from last issue could just as well have picked up here.)
The Huntress, who is wearing a Bat-logo on the soles of her boots, was created by Paul Levitz, Joe Staton and Bob Layton, and first appeared in ALL STAR COMICS #69 in 1977. (She was slightly revised post-Crisis.)
"Bat-Might": maybe she means Bat-Mite (since the character by that name got referred to as "Might" in Batman R.I.P.), but as it is this doesn't quite make sense.
Longinus's name came into Christian tradition via the Gospel of Nicodemus, several centuries after Christ. "Gaius Cassius" apparently got appended to that name in Louis de Wohl's 1955 novel The Spear. The WWII flashback here refers to incidents in ALL-STAR SQUADRON. Although, as commenter jgoldscher points out, what's the Earth-2 Superman doing here?
Catwoman, last spotted perching on a building last issue, has joined Cain's charnel cuddle-puddle; this all has to be happening long before they join the Female Furies seen over in FC.
Odd visual storytelling decision to see a speaker's back in three consecutive panels (and do three consecutive 180-degree turns on Cain). A director might say "cheat out."
So that's where the Statue of Liberty from FC #1 went!
See you in two weeks for BATMAN--it now appears that SECRET FILES has been bumped to Dec. 31. (Which means that REVELATIONS #3 may be the only FC-related title between, er, REVELATIONS #2 on Sep. 10 and the end of the year released on its originally announced release date--possibly RAGE OF THE RED LANTERNS too, depending on how you're counting.)
