It Was Always You

Prologue: Mysterious Girl

"Who is that?" Nate Archibald whispered to his best friend Chuck Bass as they were engaging in one of Chuck's favorite sports. Freshmen hunting. Up until now, Nate had no idea why he came along. He already had a girlfriend, and was desperately in love with her best friend. So for him, there was really no point to this whole thing—that was, until he saw her. "Chuck," he protested, "who is that?"

"Which one?" Chuck asked annoyed that Nate was distracting him from deciding on his next prey.

"Her," Nate said pointing to a petite girl with long blond hair that fell just below her shoulders, and beautiful blue eyes who walked along the path to Constance Billard all by herself.

"How am I supposed to know Nathaniel?" Chuck asked, a cool tone in his voice.

"Please, like this isn't a game for you and you don't know the players," Nate laughed at his best friend.

"Since you are my best friend, Nathaniel, I'll run some stats and get back to you. After all, I can find out anything. I am Chuck Bass."

"Okay," Nate whispered, images of the beautiful mysterious girl swimming in his head.

"Nathaniel, not that I am against this in any way, but you do realize that you have a girlfriend and you also have a habit of falling for girls that are slightly unattainable, even for you."

Chuck's cold reminder made Nate think about Blair Waldorf, who had been his best friend for a very long time, and, I who, as everyone liked to say, he had been dating since kindergarten, and it made him think even harder about Serena Van der Woodsen, his other best friend, who he had been in love with all his life, and about whom he was keeping a terrible secret. "Yeah I know Chuck," he answered. "But I need you to do this for me. I need you to find out who she is so I can put all of this stuff to rest." With that he walked the opposite way that the girl had walked moments earlier, towards St. Jude's.
