Rainbow Dash has had to work hard to keep up the reputation of the toughest pony in Ponyville, but when she gets involved with Twilight what will happen? Is she willing to give up her favorite aspect of herself for her favourite filly? What will the town, or their friends, think of their new relationship? What will happen at the town's big Running Of The Leaves? (This is my first fic, so it may be a little rough. Any feedback and ideas are welcomed whole-heartily.)
