Agreed. Actually, I'm thinking that one of the themes of RWBY may turn out to be that you have to work for your "happily ever after". It never just comes; you have to fight for it and build to get there.

Notice how scornful the opening naration was of building monuments to peace whilst the lights of the world fade and the darkness arises again, both from the Grim and in the hearts of man. If you want a happily ever after, you need to expend effort to make it and to keep it.
