I don't know whether to blame Johns, Jimenez, or both, but the flashback sequences as Kara regained her E-2 memories included E-1 Superman's Arctic fortress complete with giant golden key and golden door. E-2 Superman's Secret Citadel resembled more a cathedral from the front and had his S-shield above the entrance.
I had such high hopes for this series and I'm finding Johns/Jimenez/Berganza/whoever is being really slipshod on the research here.
Say what you want about Wolfman's Crisis, boners like what I've griped about in IC didn't occur there. I think the only one I can come up with was Stewart wearing his power ring on the wrong finger in COIE #1, and that's not a biggie.
Oh, yes, DoctorZero, I agree completely that the Post Crisis Mr. Atom -- along with the rest of the DCU -- had been seriously downgraded in power-levels compared with the Pre Crisis version. My unstated point was that the Pre Crisis level E-2 Superman operates at a much, much higher level than the characters of the Post Crisis DCU. On this score, Johns has successfully captured those differences.
the fortress was the silverasge supermans...
see coie for a visual reference....
she remeber's going there to mourn with kal-el not kal-l.. it's an intentional mistake so people pay attention to it..
im pretty sure one of the luthors found a crisis remenant of the key and fortress in an issue of superman recently.
