I thought of Ethan’s character being Bae and after Neal it seems like the best fit. That being said I think Bae is more important that what it seems like Ethan’s character will be. Also the writers love to make problems by having really complicated family trees, and Neal being Bae would lead to much more interesting story lines, by what I know so far. If I was to guess who Ethan’s character would be it would either be, Oz, Peter Pan ( even though I still think Bae gas this role as well) , one of the lost boys, or one of Wendy’s brothers or even her son or something along those lines
