I dont believe Emma will die, but if they were to go that route, episode 2 may still end great, but that doesnt mean she cant die off screen, and for example, if by end of 7a they would get their memories back, the viewers could be told that Emma died, and Hook decided to help Henry in Emmas memory, we cant forget that even Colin said that he only knew about Dark Hook, before he got the script of something like that, so even the actors may not know the full ending, also even if Cs has a kid (that may be a child or teen, that doesnt exclude Emma ebing dead, Disney is known for killing parents), that would give Hook another thing in 7b, being a single parent and maybe find a new love, if Regina, can have a True love that dies, and a soud mate that dies, only to probably find a TL/SM in s7, the same can happen to Hook.
Like i said before, i don`t believe Emma dies, which means maybe they may get only their memories back at the end of the season, and we dont get the reunion onscreen, probably bc if they end having a s8 or even if they dont get, some characters return to SB and others stay at the place they are now, because this season is about Henry and Cinderella and Lucy finding each other, the viewers only need to know the other 3 old characters are back at SB and happy, not need to see it, they already saw that last season.
