No, I'm not saying that there was an actual relationship there. There clearly wasn't.
I just think it's funny that we've got a 12 year old Sue here, and then we've got people saying "Well they aren't that far apart in age/maturity/whatever." Meaning that they aren't that far apart as they are at their present age in comics today, I'm sure, but in light of the above scene it just sounded... off.
And so, I was actually replying less to your specific comment than I was saying, in general, "Regardless of what else me might say about them, IF there was a relationship between them at the age pictured, it would clearly be wildly inappropriate to say the least."
