"Its star" would mean main character and the only main character Once has is Emma. All the rest make up the main cast, but it's not their story and if it says "star" rather than "one of its stars" it can't be related to Once, unless it's Emma who dies. Plus, killing off Emma is all of "not likely at all" because it would be redundant and sort of trivial.
