Quote from an interview, mentioning this episode:

Are there some returning characters that you’re particularly excited to see again?

EK: This Sunday, I’m excited for them to see what Hook looks like [in the Wish Realm].

AH: I’m just excited for more digging into the lives of our core characters, from Snow and Charming and more of their back stories, to Emma, and seeing more of young Emma — not just what you see this Sunday, but beyond that. I think that there’s a lot of really emotional stuff for all of them that they’re all going to face in the second half of this season.

EK: I’m excited for a lot of them. There’s a great Rumple story coming up with him and Bae in the early days. I’m excited for people to see the Black Fairy origin story. There’s also a really fun flashback to Storybrooke during the time of the curse that has got that real Season 1 vibe, and I think that’s a lot of fun.
