After the plot twists and developments that occurred hard and fast in the last few months in both Fantastic Four and FF, this issue slows things down and moves at its own pace. So we get a time-travel trip and a preview of 3012. Take another good look at the cover and recap page; they come into play in the issue.
end of spoilers
3012: Earth is allied with the Shi'ar and Badoon, the diminshed Kree empire stages punitive strikes with its Skrull slave troops, and is intercepted by the Fantastic Four of that era: Ben, Franklin, and two others. Ben and Franklin are the only consistent members of the various incarnations of the FF. Reed deduces that Ben ages only when he turns human, which is once a year thanks to the serum he took.
Reed and Nathaniel move forward every 1,000 years.
4012: A Ben with rocky facial "hair" addresses a huge gathering of the (apparently graduating) class of the Future Foundation, alone, as Franklin is off in space, telling them to enjoy life in the midst of making things better.
5012: An elderly Ben reminisces in his private garden about the good ol' days in front of a memorial to Johnny, Reed, and Sue.
6012: Franklin bids the now deceased Ben goodbye, in a world that looks completely different from 2012.
Reed and Nathan return home, with Ben and Bentley watching boxing, as Reed shares a drink with his best friend.
Inevitably, with a story like this, I couldn't help but remember two other scenes in previous issues. The first is in Waid's run where, after the FF storm Heaven to bring Ben back, God shows them a sketch as they are in advanced years. The second is in McDuffie's run, where after a future incarnation of the FF and Doom meet the present FF, the future FF tell the present FF that they will have more trials and tribulations, save the world (and more) numerous times, and that they'll leave the world a better place. Since both are so general, there's no conflict between what all three authors wrote.
