This being Disney's adult take on their brand, I suspect there's a happy ending for all, maybe except Regina (MAYBE). That's what I meant by Disney foreshadowing: most shows foreshadow a bleak turn of events, but, this show foreshadows Disney's happy endings for all.
That'll depend solely on the ratings, if the show ends this series I doubt it'll have much of an ending.
Have the ratings changed much? Last I heard the show was a monster hit for the network, but I haven't checked for a bit...
