What would happen to Harry if an improbable incident had tempered his susceptibility to negative emotions? If a fortunate series of events had given his thoughts space to breathe? It's difficult to say, so the best thing to do to find out is throwing the dice and see what comes up.

This is a one-shot spin-off of 'Lady Archimedes', sequel of 'The Arithmancer', an amazing HP fic by White Squirrel, but actually it could be applied to a lot more fanfictions and maybe even to the original story. In my opinion, this is what would happen if Hermione's parents were not forced to behave like NPCs by plot requirement. Divergence from 'Lady Archimedes' at chapter 23.
