PoM: that’s what Emma said but doesn’t mean the writers couldn’t add to it, since it was obviously a simplification as it left out her relationship with Neal. She wasn’t going to open up at that moment and say “A few years after the guy who was Henry’s father that I thought was the love of my life left me, I met this guy who [….]so after that one night stands are as far as I ever go.”
She never mentioned Neal then so stands to reason she could have left out other things. She still has not on screen told the story of how he left, and he has not fully explained his side either. He was sort of going into it but Emma cut him off and said it did not matter now in an angry “don’t want to hear it” way. She might be more willing to listen now that she knows he loved her along, and after seeing the long reach of “fate” that meddled in their lives. She did not still quite believe in “that stuff” at that point.
Substitute whatever tragic end to the potential in-between hypothetical relationship– he proposed and she said no, he turned out to be married, he played for the wrong team, whatever. She could have had a relationship that went bust in there and we never knew until it was relevant to the story.
Red: I hope it changes the flavor of the fandom a bit and calms down the people who keep trying to read into what Adam says in order to “prove” which way the writers are leaning on this Emma ship or in general other sub-plots. Probably not! But it is good to see Adam realizing how intently his words are taken.
