No, I haven't been following events on the Iron Man side of things, either. (I haven't really even been keeping up with Slott's Fantastic Four beyond skimming through to see if Doom appears. I end up letting the issues pile up unread for months because he seems to mostly just want to retread tired old storylines that I didn't find very interesting the first time.) I used to try and follow a bunch of comics sites and forums so I at least had a vague overview of what was going on in books I wasn't reading, but there's such a constant flood of events and relaunches and spin-offs and things that I just don't have the time these days.

I feel like Tony should at least have a bunch of questions for Doom next time they meet. He basically returned just in time to be confused about why Doom was playing Iron Man and helping out, only for Doom to promptly get injured in the battle, disappear back to Latveria and give up the hero thing again. You'd think Tony would want to follow up on what the heck that was all about at some point, out of curiosity about why he adopted the Iron Doom look if nothing else.

And I remember seeing some panels from that Brubaker storyline. I guess at least where there's time travel stuff involved it's still always possible for someone to pick it back up any time!
