This is what happens, I have no doubt, when word comes down to use a villain and build a five-issue story around him. This is pure guesswork on my part, of course. I can't swear that Paul wouldn't have done a Dr. Octopus story even without the approach of the movie. I can't guarantee that Paul wouldn't have written a five-part tale without the current push to get story arcs re-published in trade paperbacks. And as far as I know, Paul was just burning to tinker with Ock's origin by throwing in this odd little tale of a dysfunctional family. But it sure looks like a writer just coming up with something to pad out a story that he probably wouldn't have written in the first place. Whether it is or isn't, I recommend the quickest possible retcon to this flashback. Ignore it, refute it, show that Ock made it up in the telling, anything! It's in the best interest of the character.
