Of course, if he is willing to sacrifice 10 years ago, he might also do something in the finale that cuts himself off from the ones he loves again, in order to save them and everyone else. Henry and Emma would give him extra motivation, sure, but he’s also thinking of the greater good.
I think it would be a very beautiful parallel, especially as it would come after Emma and Neal have a Swanfire talk.
