Do you know this is actually a good point. A lot of Rumbellers love RUMPLE over even over Belle and by extension Neal – naturally, because Rumple and Neal come as a package deal. So they want Neal to get his happy ending more than anything, even to the detriment of other characters (Emma and Killian most notably), and (IMO) put blinders on to the fact that Neal isn’t always a good man. I readily accept that Hook’s past behaviour hasn’t been stellar, but he’s changing NOW and that’s what matters. Neal has exhibited bad behaviour VERY recently – the use of a toddler to bait Pan’s shadow (which I’m still not over not by a long shot).
It’s easy to see how Rumple fans will easily choose to support Neal over Hook. Neal like you said is a package deal with Rumple, so who would they rather support? Rumple’s former rival or his only son?
