Klaus' Daughter is a Lockwood?

What if Klaus actually had a child before Hope and she was living right under his nose in Mystic Falls. Your name is Nicole Lockwood. You live with Tyler & his Mom. You're mom left you in the Lockwood's care when you were 3 years old. You haven't seen or heard from her since. She never told you about your dad. The Lockwood's adopted you once your mother signed over all her rights to them. You are now 18 so you already graduated high school. You have golden blonde curly/wavy hair with light green eyes and fair skin.
As for your social life; you are currently crushing on Stefan who is now single since Elena is dating Damon. Caroline & Jeremy are your best friends. Bonnie isn't too fond of you because she gets weird vibes whenever she goes near you. You and Elena are civil but that's about it. Damon and you are like oil & water but you always have each other's backs. Matt & Tyler are like your brothers and super protective of you. Alaric is as close to you as he is to Jeremy. You're unaware of the supernatural entities in Mystic Falls.
