Link to Naruto spoilers over on Chuunin! Okay, so there are clearly only three possible outcomes to this fight:
1. Sasuke and Naruto sing a duet while fighting in fake opera slo-mo. At the climax of the piece they stab each other simultaneously and die, leaving Sakura to sing the final aria leaning over their dead bodies.
2. Sasuke and Naruto sing a duet while fighting in fake opera slo-mo. At the climax of the piece, Naruto stabs Sasuke and kills him, then commits suicide, leaving Sakura to sing the final aria leaning over their dead bodies.
3. Puccini swoops down and breaks up the fight, being, in fact, more ninja than the ninja.
Personally, my vote is for option 3.
Thoughts?
