Actually, the show is about Emma, her group of friends, and their interactions with others. I'm kidding. Emma is the main character and if there are villains who would they threaten her family or who...

Ariel doesn't have to interact with Ursula because it happened in the Disney movie. There is a twist. Regina played Disney Ursula in the story, why? to relate it to Snow and her story.

Frozen was the first thing introduced which had no connection but soon they connected it to the story of Charming and to Rumple. It would be nice to have a separate characters with their own story but you have to have a reason for them interacting with the main cast. If they didn't extend connections to the main cast, (which they did to at least half (Charming, Emma, Hook) while Belle, Rumple, Regina were somewhat involved), it would look like Frozen Live! with these random extras.
