I wonder is he embarassed at all to show off a new wife when they knew the old one too?
Does he think about it? Does he wish that he could remove the old one from history so that he could introduce the new to the people they once knew? Oh I forget. He did that. He took the new back in time across the continental divide and showed her to the people who knew the old. He did erase her in their minds.
Only the old is embarrassed to be replaced. Only the old thinks of these things. She is not busy being new and so remembers.
But old and new are such common occurrences that no one thinks anything of it now. It is how it is. Thatβs all.
