In an attempt to answer your questions, Henry just explained that there were infinite versions, no, and that's a good question that's never actually addressed despite the fact that the writers SAID that they were going to explain the age discrepency but never did at the right time! Of course, I just assumed that Henry must have travelled in some realms where time passed differently, but it would have been nice if they addressed this LIKE THEY SAID THEY WOULD ahem.

Also for me, if a show's at a certain level of quality then the plotholes don't matter much (unfortunately that was four years ago!) or it's fine if it's an inconsistency made years later after a mentioned fact.
