You know, that age thing is really weird.
We know Emma is 28 and MM is supposed to be around the same age, so when the curse happened Snow was that same age as she didn’t age afterwards. I also always believed Cinderella and Red being around the same age as Snow.
The problem is that in The Price of Gold Ashley tells Emma that she’s 19! That would mean she was 19 when the curse happened! She just doesn’t look 10 years younger than Emma or MM/Snow!!
Really, the only one who could play the late teen early 20 is Sean/Prince Thomas and even that’s a stretch. 😕
