I believe in what Neal said to Emma at the bar, about fate and destiny…
If it wasn’t for Bealfire to go to the another land without magic (but somehow ended up in Neverland so he wouldn’t age….) then he wouldn’t become Neal Cassady and if it wasn’t for the curse (so rumple could find his son) then Emma wouldn’t have end up in our real world where she and Neal met each other.
So if Bea was still in FTL and there wasn’t any curse at all.. then he and Emma would never find love because of the age and you know the rest… So I guess that this could be fate that tied their ways together and even if Tamara and Neal are engaged at this moment… I’m very sure that Neal and Emma will find their way back to each other… but not in a shady way like David and MM did behind Kathrine’s back… Tamara is a very pretty girl and I believe that she would let Neal go when she finally learns that his heart belongs to Emma, even when the spoiler did say thatshe will fight until she get what she wants…
Neal and Emma are meant to be together and they will always find each other. No matter where they are or what will happen to them, they still want each other happiness and love. This for me is the definition of true love, and even when they are in our real world, we must remember that they’re both from FTL…. so maybe true love rules for them too?! And they will be together because they love each other not just for Henry’s sake. 😀
