I didn't expect him either, I only expected former regulars in season 7, not even Gideon, I mean, he's tied to the family, but I wouldn't have guessed he was grown up again... oh wait, 20 years have passed, right...

I'm gonna guess Hook and Smee are part of the Rapunzel flashback. It also seems very easy to travel through EF2 if even minor characters are coming, although Smee went with Hook (likely).
