The reference to Gollum is just that, a reference. It's a cultural referent; Gollum is the threat of loss, and just in case you didn't get it (like all the people who think this actually refers to a particular episode in Tolkien), they let us know that Gollum and the Evil One crept up and slipped away with her. Gollum is a thief and murderer who lurks in the shadows, but is never far away. Think of him as malevolence, either in fate or in another person.
