(First Sparity fic)

With everything going on in his happy life in Ponyville, the adventures, the fun, the lessons on friendship, Spike never took time to have any appreciation with his time with it all, assuming his life would always be this happy. Then that letter came... the letter that had it spelled out right in front of him that he was never supposed to happen, that he was never supposed to even live, and that Twilight must make the difficult choice of choosing her friend, or her princesses orders. As Spike finds anger inside him build up from seemingly nowhere, he storms out of the house, into the twilight of the night, tears streaming down his cheeks.

All the while, Rarity is there to comfort Spike through his emotions, his feelings, his fears that one baby dragon should never handle on their own. She begins to realize just how important Spike is to her, not just as a friend. As the days of his happy life tick by second after second, just how dirty is Rarity willing to get just to save a dragon's numbered days?
