During the episode darkness on the edge of town, Brooke does not wake up but rather falls into a coma. While in her coma, Brooke explores the roads that she didn't take in life with Keith as her mentor.
NOTE: Flashbacks will be in bold italics and the future parts will be unbolded italics. The present will be in plain font, just to clear any confusion up.
An array of bright lights surrounded her as she blinked, struggling to figure out what the hell was going on. The last thing she remembers is having a fight with Julian about moving to LA.
"Well, well if it isn't Brooke Davis. I was wondering when I'd get to see you next."
She would recognize that voice anywhere. She's surrounded by blank white walls and she can't figure out where the voice is coming from. "Keith?"
"Over here."
She turned and sure enough there he was. She hadn't seen him since he died almost a decade ago. "So how have you been Brooke Davis?"
"Keith, what are you doing here?" she asked as she ran over to him and enveloped him in a hug.
"I'm here to show you the paths in life that you never took. Fate had six different plans set out for you. I'm here to guide you through the what ifs. There are five different roads that you opted out of, five different relationships that could have shaped your life differently."
"I don't understand," Brooke shook her head. "Why am I here? Why are you showing me these?"
"You almost died Brooke," he whispered as calmly as he could muster. "There was an accident…"
"An accident?" Is everyone okay? Are Nathan and Haley okay? Is Julian okay? Please tell me he's okay…"
"You don't remember?"
She shook her head. "The last thing I remember was getting in a fight with Julian and running off."
"A car collided with Lauren's. She was driving Jamie, Chuck and Madison home from the spelling bee. You came across them and managed to save their lives Brooke."
"But what about me Keith? If I had saved them, why am I here?"
"Because you risked your life to save everyone else's. Another car came by just as Julian arrived and was ready to help you free Jamie from the vehicle. It hit Lauren's car and pushed you two off the bridge. Julian jumped in to save you but your leg was stuck and you insisted that he save Jamie first. The dam burst and Julian managed to get Jamie out before coming back for you. He barely managed to save you and when he got you out of the vehicle, he performed CPR on you but you never woke up. You are currently in a coma in the Tree Hill hospital."
"H-how come I don't remember any of this?"
"You hit your head pretty good while you were fighting for your life Brooke."
"I understand that you are getting married next month," Keith smiled at the girl that he'd always thought of as a daughter. "And it is my job to prep you on what could have been. It might make you change your mind before you marry this boy."
"I love Julian and I want to marry him. I have no doubt in my mind that he is the one for me."
"That may be so but haven't you ever wondered what if? Haven't you ever wondered where you might be in life if you'd chosen a different path, a different boy?"
"Yes," she admitted as a small smile crossed her face.
"Now here's your chance."
AN: After watching darkness on the edge of town I got this idea. It won't be a very long story. About seven chapters I think. Keith is Brooke's mentor and he guides through the roads that she never took in life. Couples will include Brathan, Brucas, Brase, Bray, and Browen. I have different ways of being them into the story. Because Bray and Brathan did not happen on the show I have my own versions of their relationships. The first chapter will be Brathan since they happened first on the timeline. Please review and let me know what you think.
