There were worlds much like the one they lived in now, and worlds that were different in every conceivable way. There were worlds where they were both human, worlds where they were both Sidhe, and there were worlds where they were some other kind of creature altogether. There were lives where they found and lost each other quickly, and lives where they stayed together for years upon years. There were lives where they loved free and proud, and lives where the love they shared got them both killed. There was every kind of barrier and every kind of victory. There were lives of misery where they never truly saw what they were to one another, and there were lives like precious jewels where they found each other so, so young and saw one another with clear eyes from the very first moment.
And in every life, in every world, their essences were unmistakable. They were Kurt and they were Blaine, in any language, in any interpretation. It was always them.
