It all makes sense. Dan was standing next to Chuck and heard what he did for Blair in 2x24. That's why Gossip Girl was clearly Team Chair in that episode, stating "Who knew the mother-chucker could also play fairy godmother?" and "Why does it feel like our queen is standing with the wrong king?"

Sneaky little Dan.

Enjoy this one shot :)

Blair didn't know how long she had been seated on the steps outside of where their prom was. She had been sitting there, contemplating her break up with Nate. Ending things with him had inspired something new in her, something mature.

Was this what growing up was? If so, it wasn't so bad. She felt sad at leaving a huge chunk of her adolescence behind with Nate, but that was it. It wasn't that deep loneliness and despair that she felt when she had no idea where Chuck was after his father passed away, or the heartbreak she felt when he told her it was just a game.

But it wasn't a game. Everything that he had said, and the look in his eyes when he had said them. Everything that he had done. All the things that she had said and done. It all proved that there was something heart-wrenchingly real between them. He was just afraid, and she was too now.

"Hey!" Serena called, joining her on the steps, "Where's the prom king?"

"We broke up" Blair said quietly.

"What? But everything was so perfect, it was like a fairytale" Serena said.

"Turns out fairytales end when they do for a reason" Blair said with a small smile, looking so unlike her usual self. She looked wiser, and in less denial.

"I really wanted to go to prom with my high school boyfriend, and now that I have-"

"He feels like your high school boyfriend" Serena finished for her, "I'm sorry."

"Me too...that you almost missed prom because your mother had you arrested and your quasi-half-brother slash ex-boyfriend was your prom date" Blair said, still having some quirkiness in her. Serena giggled in response.

"You know I actually had a lot of fun tonight. Dan and I made up, and I know that whatever my mother did, she did out of love. And right now I'm with exactly who I want to be with, my best friend" Serena stated with a smile and Blair had to grin back.

"You are high-school to me. All of the boyfriends and mean girls, and tests and teachers and our crazy mothers. We went through it together, we raised each other. You're my sister" Serena continued, giving Blair a squeeze.

They both smiled at each other and just sat there in happy silence for a few moments. Blair felt some happy peace with her best friend for a few minutes, but it wasn't long before thoughts of Chuck began consuming her mind, filling her with questions.

"Can you believe Chuck tonight? He almost ruined everything" Blair blurted out of nowhere.

Serena turned to look at her for a moment with a pause. Did Blair really have no idea about anything? As Serena studied her further, she saw something that surprised but thrilled her too for some reason. There were flashes of hope in Blair's eyes. Maybe she wanted Serena to beg her to divulge everything in her heart that moment. Maybe Blair wanted to talk about Chuck because it made her feel close to him when she couldn't be. Or maybe she wanted Serena to tell her something about Chuck.

Serena couldn't ignore the feeling in her gut she had been having ever since she knew the depth of Chuck's love for Blair. Chuck was a bastard, and hadn't been perfect to Blair. But the love he had in his heart right now was sacrificial, selfless and terribly romantic. And his facial expression when he had been watching Blair on the stage, a light in his eyes with a small smile. Seeing her happy made the boy who had every reason to be troubled look peaceful, for a moment. Serena shivered on behalf of her best friend.

When Serena hadn't replied for a minute and was staring at Blair with a funny expression on her face, Blair knew something was up.

"Spill it"

"What?"

"You know something" Blair said, narrowing her eyes.

"Blair" Serena sighed.

Blair clutched Serena's arms and looked at her. Serena caught that hope again in her eyes and then she knew. Blair wanted anything, she was desperate and hungry for anything Chuck-related. Serena would have been worried about the level of need that had been running through her best friend's heart, but not when she knew how much Chuck loved her. His actions had left Dan speechless, and Gossip Girl had even said that it felt like Blair had been standing on stage with the wrong king.

"There are some things you should know" Serena said slowly.

Blair nodded in response, her eyes widening.

"Tonight, everything went perfectly because of one thing and one thing only. Chuck" Serena said, watching her friend carefully.

"What do you mean? He was trying to sabotage me if I'm not mistaken" Blair replied, confused.

"I mean, that I'm apparently not the only one who knew about the scrapbook."

Blair's eyes widened further as she began to ask Serena everything.

"My dress being ruined...and the even better replacement that was identical to the one I drew?"

"All him"

"My corsage?"

"The dress looks better without it, his words."

"The limo?"

"You had a carriage instead, like a real fairy tale."

"Me winning prom Queen? He was trying to ruin my chances!"

"He was taking the Nelly Yuki ballots out, and then voted for you 150 times" Serena exclaimed. Blair looked away from Serena for a moment, her heart beating hard in her chest at the unexpected news.

"The hotel room?" she asked with a small voice.

"He uh, asked me to give this to you. But now that you and Nate have broken up there isn't much use for it" Serena said, handing her the key to the penthouse at the Plaza. Blair stared in wonder for a moment at the key. When she looked back up at Serena, Serena was taken aback by the tears in Blair's eyes and the hopeful smile on her face.

"Why would he do all this S?" Blair whispered.

"He said that he just wanted to make sure that you had the perfect night. Blair, I've seen it first hand all year because I live with Chuck, and I know that he was dying to be with you. " Serena explained.

"But...I asked him if what he felt for me was real and he told me it was just a game," Blair said softly, sniffling slightly as Serena told her everything that, deep in her heart, she desperately needed to hear.

"And I knew he was lying, so I asked him why he said that" Serena said, a smile appearing on her face as she prepared for her friend's reaction. Blair looked at her beseechingly.

"He said it was because he loved you, and he couldn't make you happy" Serena whispered, then bit her lip in excitement. Serena suddenly thought that she really needed a boyfriend or a hobby, because she was starting to get too invested in her best friend's love life. But being a romantic, she couldn't help but be fascinated by her step-brother and best friend's love for each other.

Blair gasped as more tears appeared in her eyes, finally letting her emotions all show. Serena put an arm around her friend and squeezed her. Blair closed her eyes for a moment and took a couple of deep breaths, but she couldn't keep the smile off her face.

"He really said that?" Blair finally asked in a broken voice, a watery smile on her face.

"Yes, B! And look at how happy you are. Maybe he should just say the three words next time instead of going to all the trouble of planning your perfect prom, if he's so concerned with your happiness" Serena said with a laugh.

Blair had to laugh despite herself. Actually, Blair could laugh at anything right now, so consumed was she with giddiness.

"Do you think we'll ever be together S?" Blair asked suddenly.

"We're already together, B" Serena said with a cheeky grin. Blair rolled her eyes and hit her friend playfully.

"You know what I mean."

"I think...that you two have to end up together" Serena said softly, the mood becoming too serious for her liking. What if Chuck Bass never manned up for Blair?

"Otherwise, which other pair is going to defend my honor and take down the annual manipulative psycho-bitch trying to ruin my life?" Serena said with a wink and Blair giggled in response.

I kind of want to turn this into a two-part story where Blair actually ends up confronting Chuck about this in the next chapter. Review if you would like me to do this.
