...the showrunners were asked about when The Little Mermaid’s Ariel might finally make an apparance. “Probably not this season,” Kitsis admits. “We’ve taken a lot of toys off the shelf, so we’re probably not going to see her this year. We do have a plan for her, if there is a Season 3.” link after winter break, this season will be all about the charming, regina and rumple, they even push aurora, mulan and phillip story
I really want to see ariel on OUAT, she's one of my fav princess, but I guess we have to wait :'(
