They never showed what Cap saw right? There was no Captain America issue of Original Sin, and the Avengers Original Sin tie in didn't have anything to do with the watchers eye, and the spell that has been shown to be wearing off in Steve's nightmares throughout the series just wore off, so what could Cap have seen?

Maybe he knows about Maria Hill's Secret Avengers since it was teased that it will be going public at some point?

It wasn't him remembering the Illuminati, right? He just remembered that randomly?

Yeah he remembered that randomly after waking up. He was all pissed off from just remembering it in Avengers, and in the first issue of Avengers you can see he is already starting to remember it in nightmares.

@teerack: Hm…then I have no idea what it could be. That's really weird. I wonder if Remender has that on back story. I hope it's not a dropped plot line.

I was under the impression that it was the whole mind-wipe the Illuminati gave him in New Avengers. There's really nothing else I could think of as they haven't hinted at it being anything else but that.
