ok 3.12 is about Hook and Emma is this going to be parallel story like Neal and Emma was but reverse.
1) Hook meets Emma 1st instead of Neal meeting Emma in the car.
2) New guy could be Emma’s fiancee like Tamara was to Neal.
3) Hook talking to Emma at the park like Neal was with Emma telling her about the watches.
4) Hook was arrested instead of Neal
As for the family tree I agree with RG which is rare 🙂 –This will be Snow’s baby and David’s father if you look back to Adam’s original first tweets he stated that we would get more of David’s back story this season.
