AN: Like many, I've been going through GG (and especially Chair) withdrawal as the fall TV season is approaching and there's no new episodes. So to fill the void I've been rewatching episodes and reading fanfics on sites like this one. I was a bit disappointed that I could not for the life of me find any fanfics that take place during episode 100 (5x13) with Blair running from the alter and deciding at the last moment not to marry Louis, so I figured I'd give it a try so that there's at least one story like that out there! (Feel free to post links in the comments if you know of any though – I'd love to read them!).

So this takes place on the day of Blair's royal wedding. It was originally going to be a one-shot, but as I wrote it, it automatically formed into chapters. The first few scenes are verbatim from the episode, so they will seem very familiar, but then the story changes into how I (and I'm sure many Chair shippers) wished the episode would have gone.

Enjoy!

Where was her mother, Blair wondered as she nervously waited in the bridal suite with her chosen bridesmaids. They said Eleanor stepped out for something but all she was doing was holding up the wedding.

This dreaded wedding.

As much as she wanted to live a fairytale life as a princess, she knew deep down this was all wrong, yet she had to go through with it and now just wanted to get it over with.

Penelope was rambling on about something when Eleanor walked in.

"Out. Everybody! Out – out!" Eleanor demanded.

"Mother... where have you been? Everyone's been looking for you..." Blair inquired.

"Don't be angry with me..." her mother started.

"Angry with you..?" Blair wondered. What had her mother done now?

Before she could say another word, in walked Chuck.

Oh why was he here? Was he really here to try and stop her? He should have just stayed away today – all he was doing was making this day even harder for her.

"I'll... just leave the two of you alone..." Eleanor said as she stepped out into the hallway.

"What are you doing here?" Blair demanded.

"Trust me, the last thing I wanted to do was show up today but even your own mother seems to think we need to talk..." Chuck explained.

"Well what I need is for you to..."

"Don't marry him," he interrupted.

"Chuck..."

"Don't marry him," he repeated. She knew he was right.

"All those people out there are waiting for me..." she started. She knew it was just an excuse but she had to go through with this.

"Yes they are. But they also want you to be happy, which you're not going to be if you go through with this. Tell me I'm wrong and I'll leave," he said. "You can't... Because it should be us out there and you know it."

Once again, she knew he was right. She really did wish it was him and her out there – Blair and Chuck, Chuck and Blair, just like they always are.

"It isn't that simple..." she began.

"It's only that simple. You told me you loved me. I know it was true."

"It is! Of course I love you, Chuck. I've always loved you. I love you more and more every day if it's even possible to love someone that much!"

"Get out of here with me right now. We can go anywhere just as long as we're together."

Every part of her desperately wanted to do just that – run off with Chuck, the love of her life, and end this nightmare. Yet she knew she couldn't. She was too scared of what would happen to Chuck if she reneged on her pact.

"I know you can't understand, and I don't expect you to, but even if I weren't with Louis... I couldn't be with you. Just know that not living with you is the hardest thing I've ever done. But at least I have someone who loves me by my side. you should find someone who loves you too."

"I have. She's standing right in front of me." Chuck told her.

"I know it sounds crazy, but I really am doing this for you." She was fighting back tears now. She knew marrying Louis was all wrong. She wanted nothing more than to be with Chuck. Yet she had to go through with this.

There was a knock at the door. In walked Serena.

"Hey, B... the photographer's ready..." Serena said as she noticed Chuck in the room. She was about to inquire what was going on when Blair spoke.

"It's okay, S... Chuck was just coming to give me his blessing. Right?"

Chuck shook his head in disbelief. He could not believe she was still going to go through with this. He knew she didn't love Louis. Everyone knew it. Her own mother had even brought him there hoping to stop it and yet that didn't work. What was Blair doing?

Serena pulled Blair into a side room.

"What is going on? It's time!" Blair demanded. What was with everyone dragging this out? First her mother and Chuck, now Serena. She just wanted to get it over with.

"B, are you sure you feel right about all this? Because I am totally prepared to make a run for it with you if that's what want..." Serena said.

"I have made peace with my decision... and so should everyone else."

"Okay, if that's how you really feel."

"It is." The tears were welling up in her eyes again.

"I know you think you can't be with Chuck, because of the pact you made with God, but maybe the pact is just an excuse you're using to protect yourself from... from the messiness and uncertainty of a life with the man you really love!"

Serena had a point. Maybe it was just an excuse. But what if she broke the pact? What would happen to Chuck? She couldn't bear to lose him completely, even if they couldn't be together in the way they ultimately wanted.

"I'll grow into loving Louis – I'm sure of it," she told Serena. Yet she really wasn't so sure. "And he'll never hurt me."

"He won't have to – you're hurting yourself enough by marrying him. B, no matter what's happened between you and Chuck, the two of you have always been connected – everything that you've gone though, keeps leading you back to each other, just like it does Dan and me. I know that it scares you and I know it's a risk, but don't enter into a false life because you're afraid to face your real one."

She really wanted to believe Serena. The risk... she'd rather be happy with the man she truly loved for however long they had together but if anything happened to him she knew she'd regret it for the rest of her life.

Just then her mother burst in. "I... I am so sorry, I don't know what I was thinking..."

"Mom, it's okay. I understand why you brought Chuck. But, despite everyone's protestations, I'm going through with this." Blair let out a deep breath. "Serena, will you please tell everyone I'm ready to begin?"

She had to get this over with – it was now or never.

Everything in the sanctuary looked beautiful and perfect. Everything except for the groom.

"I'll grow to love him, for Chuck's sake," she thought to herself as she made her way down the aisle with her father and Cyrus on each arm.

The ceremony began.

She was there but her mind and heart were in another place. What was she doing?

Out of the corner of her eye, she saw him slip into the back of the sanctuary.

"Chuck..." she mouthed. He was still here.

Serena and Dan saw him too. As did Louis. The infamous line in the ceremony was approaching – was he really going to make one last effort to stop this?

"If any man can show any just cause why these two should not lawfully be joined together let him now speak or else hereafter forever hold his peace," the priest declared.

Blair looked at Chuck, giving a little shake of her head for him not to. Serena looked at Dan, Dan looked at her. They both looked at Chuck – someone needed to do something. This wasn't right.

Chuck had just begun to turn around and leave when everyone's phone's started buzzing in unison.

"Oh no," Blair thought. "It was Gossip Girl. What had she posted just now?"

If no one else is willing to say it, I guess I have to. The person who should be objecting isn't Chuck Bass, but the bride herself. Don't believe me? Watch this.

Blair heard the audio on everyone's phones begin at once. Her heart sank as she heard her voice.

"Of course I love you, Chuck. I've always loved you. I love you more and more every day if it's even possible to love someone that much."

Louis looked hurt and confused. His family furious. She had to get out of there.

And so, she ran.
