theres a possibility they will have a kid since 1 of 4 things, 1 being that in season five (i forgot what episode) emma and hook enter emma's home but in the underworld's version of it has all her nursey items in the living room which could imply that she will be pregnant. Number 2, can back number 1. Killian also chose the house as a symbol to start their new future once they get out of camelot. Number 3, in the final scene emma and hook portay q conversation where a wedding dress is behind them which could imply a step in their relationship and maybes a baby? And finally reason 4 which is a long shot but tbh everyone as been having babbies and i dont think Cinderella would mind another person in her first-time mother club thing.
I think the gender should be a girl and her name should either be Charlotte, Charlie for short, Claire, or Snow in honor of Snow White since Once Upon A Time is very big on giving characters names of other characters' deceased loved ones because that's what Regina did with Henry, The Charmings' did with Neal, and Zelena did with Robin.
SHADS THE TWO BEST FRIENDS yes there is. It may take a while as I can't start it for the next couple days and I need to find some clips but there will be a part 3 which will be the final part
