Is thier going to be a season 4?

I don't think any1 knows for sure, but there might not be, because I heard they give up their powers and mermaidness at the finally of season 3. But if there is, I hope it brings back Emma, but still has Bella, and makes it mais adultish-PG 13 kind of show. Sorry it really isn't an answer. D:

i hope there is gonna be a season 4 but dont know for sure it could be the end
