Okay so maybe something odd happened that night, but It didn't change anything about Twilight Sparkle and Sunset Shimmer's friendship. Okay so maybe it did. Maybe they've become more than friends, and maybe they haven't told anyone.
Things are going fine. Twilight has to live in Equestria, of course, but Sunset has decided to stay. But then,
another Twilight shows up. And this one wants Sunset this much more.

Rated 'Teen' for passionateness and deep kisses... I guess.
