What is your take on Franklin Richards being responsible for the Marvel timeline existing for so many years in real time, but only a fraction of that in the 616 universe? It seems that when he aged to a teenager, he had a need to revert to toddler/child state. Almost Peter Pan-ish, not wanting to grow up. Is Frank secretly the engine that controls the Marvel U? Hard to believe he perished in AoU. I personally believe he altered time and escaped...
I think it’s a fun fan conjecture, but it doesn’t work at all within the context of the Marvel Universe. So from our standpoint, it’s simply not true.
