Derek waits patiently at the front of the church, his hands folded together neatly as he watches the door. "Are you nervous?" Hotch asks.

"No, I am getting a little impatient though." He grins.

"She's probably just fixing her hair."

"Come on Emily, he's waiting." JJ says to her best friend.

"I can't." She grips the arms of the chair.

"What do you mean you can't?" Penelope asks.

"I can't do this, it isn't right."

"You just have cold feet, once you see him, you'll feel better."

"You don't understand. I don't want to do this."

"I'll be right back." Penelope leaves JJ to handle Emily while she goes to find Derek. She opens the doors to the chapel and everyone turns to look at her. She gets to Derek and leans into him. "We are having a bit of a crisis."

"What is it?" Derek's eyes go wide.

"Just come." She takes his hand and leads him to the room with JJ and Emily.

"Babe, what's wrong?" Emily looks up at the sound of his voice and Penelope pulls JJ out of the room.

"I can't do this." Tears pool in her eyes.

"I thought this is what you wanted."

"I do, but not like this, not here." She wraps her arms around him. "I'm sorry."

"It's fine." He rubs her bare shoulder. "Can you tell me why?"

"It's all wrong, I shouldn't be wearing a white dress, I shouldn't be in a church, and I definitley shouldn't be marrying you."

"Why can't you marry me?"

"Because you're too good Derek. You deserve someone better, less broken."

"Emily Prentiss, you are not broken. I love you more that anything in this entire world. You may have made so tough choices, but that doesn't make you a bad person. In my eyes you are perfect, who cares what anyone else thinks."

"My parents couldn't even make it."

"Screw them. If they can't take an hour of their time to see their daughter get married, then you don't need them. You have a chapel full of people waiting for you, are you going to let them down, or are you going to go out there and marry me?" She smiles at him.

"I'm going to marry you." She places a soft kiss to his lips before they walk out. The rest of the ceremony is a blur, neither one really focusing on the words, just each other, but there are two words that Derek does focus on.

"I do."
