Based off the Taylor Swift song: "Speak Now", everything else belongs to CBS.

Penelope Garcia still couldn't believe she had actually shown up at where she was forbidden to come. Not by Derek Morgan of course. Oh no. By his lovely wife to be Tamara Barnes.

Just the flashback coming into her thought pattern caused her to grip the steering wheel tighter. Derek didn't know what he was getting himself into. Tamara was high maintenance and how Pen liked to describe her, a man eater.

She could even fool a innocent guy like Derek Morgan into marrying her. And that's why Pen was sitting in her car in front of the church right then. She wasn't going to let him say a single vow without hearing her out. She couldn't allow it.

She slowly got out of her car and made her way across the parking lot. There were plenty of people here, but it was so crowded at the door Pen didn't have to show her invitation. Which was a good thing since she didn't have one.

Tamara and her bridesmaids were in the back room of the church with the door slightly ajar. They all looked like supermodels in their perfected dresses and all the other traditional wedding things they had. Flowers, Organist and most of all poor Derek standing at the altar wearing a tux, looking handsome like always.

He hadn't seen Pen yet so she made a beeline for the curtains and hid. She still didn't know why she was doing this. To save her best friend. That was what she wanted to believe. But then again she was desperately in love with him too. There was no way she was letting him marry a girl that was wrong for him.

The organist started to play a song that sounded like the death march and everyone began to stand just in time for Tamara to breeze down the aisle. She looked stunning, even Pen had to give her that. Her Dad handed her off to Derek and the whole ceremony began.

Reid stood next to Derek as his best man. Tamara's sister was the maid of honor that was standing a little too close to Reid. Way to be subtle, Pen thought as her eyes scanned the room for the other team members. Rossi and Hotch were sitting close to Derek's family and JJ and Emily were with them. Had any of them even realized she hadn't even received an invitation? If she hadn't heard Reid asking JJ to come and be his date for the reception last week, she wouldn't have even known when the wedding was.

The preacher man was reading from a worn out book and between all the words his raspy old voice was saying Pen could make out a few words:

"Speak Now or Forever Hold Your Peace."

Suddenly Pen was on her feet, emerging from the curtains and saying: "I have something to say."

Gasps filled the church as they turned to see the red haired tech girl standing up for what she believed in.

Pen couldn't completely see Derek's face but somehow, someway she knew he was relieved.

She had almost saved him. It was her time to..

Speak Now.

I'll update soon. : ) Please Review!
