She's only alone if she chooses to be. If she wants to live a hermit-like life, then she can choose that. If she wants to have friends and other lovers, then she can do that as well. Sure, there will never be another Vinyl, but that is why we need to cherish the time that we do have our loved ones, because we'll never know if they'll still be around when tomorrow comes. And even if they're gone, we can still honor their memory by remembering the good times we had with them and remembering the what ethics and morals they valued.
