It had been nearly 3 years since Dan and Blair kissed for the first time in that hospital corridor. In those years every part of their lives had changed significantly. Sophia had bounced back and was now a toddler and just as cute as ever with flowing curly brown hair and the brightest grin ever. Living in the Upper West Side, the threesome looked like any other family but Blair made sure they were in fact the best dressed family in a mile. Engaged with a kid at twenty years old Dan and Blair held much more responsibility than the rest of their age group and at points often felt like they were 30 years old. Career wise-Dan was in the process of publishing his first book, an expose of the Upper East Side. Dan decided not to go to college because he knew he could not go and simultaneously raise Sophia, a choice that was difficult for Dan (and for his father to swallow) but one he knew was best for his daughter. Not going to college only made Dan more determined to write each and every second he could, it also gave him loads of time with Soph. While Dan perfected his book Blair attended NYU. Blair had taken her newfound 'mommy roll' in her stride. Eleanor had been less than thrilled about her daughter playing surrogate mother but she eventually warmed to both Dan (her soon to be son-in-law) and Sophia being part of the Waldorf family. Baby Sophia's biological mother remained a mystery to the Upper East Siders who reluctantly moved on to other juicier gossip when they realised Dan wasn't letting slip anytime soon. Serena had pretty much moved on with her life and rebounded with every eligible man in the state. Blair and her former best friend hadn't spoken since graduation day which literally was years ago and Serena couldn't even look at Dan in the eye. She had quickly realised how unfair their arrangement was on him and also how hard it would be for her knowing her daughter was with him and Blair playing happy families- just one cab ride away. Regret and frustration regularly hit Serena like a torpedo but she never let it show.

Blair slowly carried the cake towards the crowded table, careful not to let any of the 3 candles go out. She began singing with a big smile across her face "Happy Birthday..." and basked in the glow radiating from Sophia's bright and surprised face as she saw the cake coming towards her. Sophia sat on Dan's lap wearing a frilly pink dress and her signature wide smile. At three years old she had the whole family wrapped around her fingers. Rufus, Eleanor, Cyrus, Vanessa, Jenny, Dan, Dorota and the mothers' of toddlers Sophia had "befriended" sang along too.

"Make a wish Soph." whispered Dan before he helped his daughter blow out her candles

Following the party Sophia lay napping on her Aunt Jenny's lap in the living room, completely worn out by the festivities. Vanessa, Dan and Blair laughed as they were cleaning up the mess left behind by the screaming toddlers and family members.

Outside as the sun was setting a pair of heels clipped to the top of the building's steps and a pink envelope was placed into the "Humphrey-Waldorf" mail slot. Later when Dan opened the envelope addressed to 'Sophia B. Humphrey' which was weird because hardly anyone knew Soph's middle name. He found an unsigned birthday card that read "Happy Birthday Baby Girl. See you soon xoxo"

Panic shot through Dan. Who was the card from? 'Baby Girl' made him automatically assume it was Serena but then he took a double take at the 'xoxo'. He looked at the envelope again and the 'B.' stuck out-if this was Gossip Girl she'd have to have seen Sophia's birth certificate which stated Serena was her biological mother and then their three year old secret was out.

"No, it can't be." Dan shook his head in disbelief

"What is it?" asked Blair worried by Dan's expression

Dan remained silent and just handed his fiancée the card so she could read for herself. It took her a minute to catch on but then she gasped audibly.

"Serena or Gossip Girl?" she asked still shocked. Dan shook his head not knowing and not quite sure which scenario he'd find worse.

I'm sorry but our story has come to an end. I hope you've enjoyed the story and I know you probably hate me right now for the cliff hanger but I had to leave it on a high. Look at it this way you can decide what happens- Serena or Gossip Girl? Review please since it's the last chapter and besides I want to hear who you think it was! Thanks so much again,

Will sorely miss this story xoxo NickKnack ;P
