Actually, now that I think back on Jonathon Hickman's run, there was an issue about Franklin's birthday party. Now they never specified his age, but it was treated like a "milestone" birthday for the kid and I remember assuming that it was his tenth.Yeah, I just read the latest issue. Like you, I'm a bit muddle on just how old the kids were when the family went a traveling. Franklin was born near the dawn of the Marvel Age (way back 1968!!!!) Yet he was less than a decade old when they left???????
