I must admit, I was skeptical when I first took notice of this. I had no idea how Mercutio x Tybalt would work, but then I read it. I applaud you, because this was marvelous. I works with all the comments Mercutio makes in the play, and it's alternate-universe at the same time. This is definitely getting bookmarked for later rereading. Bravo.

Very nice! I always saw Mercutio and Tybalt's hatred for each other as repressed sexual tension. Haha. I love how you made it gradual. Great job. :)
