Thanks, BJ and Michael! A few comments...
BJ - Maybe my impression of Herb is different from everyone else, but I always viewed him as a bit scatterbrained. My thinking here is that he knows that their histories are different, but it never occured to him that he had to tell Superman that. Their lives were mostly the same aside from this one thing (even though it's pretty significant), so he said they were the same.
He may also have assumed that Clark would tell Superman. The fact that Clark repressed these memories and they are hard to talk about (and potentially somewhat embarrasing - won't Clark feel even worse about himself if he finds out Superman had the same experience but was better able to deal with it?) just never occured to Herb. This is precisely the type of "subtlety" I can see him missing.
Michael - I'm still not willing to answer questions about whether Chad is someone to be worried about or not. Although I'm not sure it will take more than a few more chapters for it to be fairly clear.
I will shed a tiny bit of light on him, though.
This is not the first time he's been mentioned, sort of.
In Chapter 15, Superman mentions his wife's Chad, briefly:
He could suddenly understand the tones Lois, his Lois, used when she talked about the Clark from the other universe. Her words were always deliberate, as if she was trying to shield him from knowing what she really thought, and she spoke softly, in hushed tones, a voice she typically reserved for when she spoke about Chad – the only serious boyfriend she had had before Clark who had not behaved appallingly and broken her heart.
But, of course, as with Clark and Superman, the two Lois' have had a different past. And as the Clark flashbacks highlighted these differences, the Lois/Chad flashbacks will do so as well. Sort of - since we know so little about the original Lois' experiences with Chad. Expect it to take to the end of the story (another 25-30 chapters) before you really know enough about Superman's wife's relationship with Chad to understand all the differences.
BJ - I'm glad you really enjoyed the flashbacks. They have been my favorite part of this story to write. BTW - forgive my shorthand ignorance, but what is RFO?
Sorry, I know I moved back and forth between your comments. My poor excuse is that I'm tired (it's about 11:30pm here) and I just got home from work. But I wanted to write now as I may not be online with enough time to do so again until Wednesday.
