So I have a theory on why Ursula is in the LWM. Ariel. She's a mermaid, mermaids can cross between realms and it's confirmed that Ariel's coming back, which means she's most likely going to interact with the REAL Ursula (although considering they didn't mention anything about Ariel being a mermaid princess in Once, I doubt it's 'cause Ursula wants to rule Atlantica...)

My theory is that Rumple somehow strips Ursula of her powers and hurls her into the sea, hoping the sea goddess drowns (ironically!), and Ariel saves her, as she's done with Eric and Snow. Since we have no idea when the QOD arc takes place, I'm going to hope it's pre-Snow Falls or at least pre-Ariel so that our resident red head still has her voice. She speaks with Ursula who tells her the situation and Ariel takes her to a land without magic, where Rumple cannot follow. No idea why Cruella's in the LWM, as well however.
