A/N: Everyone seems to write a story similar to this plot.
Chad was sunbathing outside the Mackenzie falls studio. While he turned to reach the suntan lotion, he saw a small figure running towards him. He raised his sunglasses to have a good look at the figure.
Chad's long lost daughter ran up to Chad. "Daaaaddy!" she jumped into Chad's arms. A dumbfounded Chad stared blankly at the blond girl with a face that was almost identical to Sonny's.
"WHAAAA?" he shouted, turning to face an suddenly aged Sonny. The older Sonny had deep wrinkles, she clutched an bottle of alcohol in one hand and a cigarette in the other.
When Sonny opened her mouth, her once sweet voice was rough and harsh. "Hey, love, after that one nightstand. I pooped out this brat." She wheezed and began coughing. Chad turned back to the little girl in his arms, "Oh. My. God."
The little girl tugged on his Mackenzie falls tie, "Daddy, now that you're my Daddy, can I have a pony? And a big house for my pony and a prince with my house and a great big chocolate fountain and- and- and-"
Chad's screaming drowned out the little girl's chattering. He snapped his neck to Sonny, "Since when did we DO it? I only went out with you for a week! I didn't do anything!"
Sonny shrugged, "This is a fan fiction. Anything can happen." She inhaled her cigarette.
"Sonny, what happened to you? Why are you old?" he asked blankly, Sonny shrugged again. The little girl yanked on Chad's tie again, suffocating him. "L-let go, kid." he gasped as the little girl let go her grip on his tie. "Look, I don't know what's going on. But I am NOT your Dad." He had a sneaky suspicion Sonny was trying to get money from him, judging by the state she was in. No. She isn't getting ANYTHING from Chad Dylan Cooper. he thought. The little girl hopped off his knee, "I'll prove to you I'm your daughter!" she sharply pointed at Chad's nose.
"Fine." he said firmly, "Fine," she answered. "Good." he replied, "Good." She glared.
She ran away from Chad and stopped to turn, "Peace out, suckers." Then she disappeared from sight.
Chad stared at the spot where she repeated his infamous line. "My god. She IS my daughter!"
