Emily, Riley and JJ arrived at the BAU quickly.

"Can I take her?" JJ asked softly.

"Yes please. I don't know how long this will take," Emily explained.

"Go get him girl," JJ said smiling.

"Thanks, Jayje," Emily said winking back.

"Come here sweetie. Auntie JJ is gonna take you to visit Auntie Penelope, okay?" JJ asked sweetly to Riley.

"Yay!" Riley clapped with excitement. They walked towards Garcia's office while Emily walked towards Derek.

"Derek," She called.

"Yeah, Emily?" He asked.

"We need to talk," Emily said.

"About?" Derek asked confused.

"You…me…Riley…" Emily began.

"Oh," He said catching on, "Yeah let's go somewhere private," He said nodding. I followed him to Garcia's office.

"Can we kick you guys out of here for a minute or two?" Derek asked.

"So you can do some serious making out? Of course!" Garcia said picking up Riley, who squealed with delight at the sight of Derke.

"Hey, princess," Derek said kissing her forehead.

"Daddy!" The little girl exclaimed.

"We'll go play in a couple minutes ok? I have to talk to mommy, first, though," Derek explained.

"Will you kiss kiss like Auntie Penelwope says?" Riley said sweetly.

"Did Auntie Penelope say that?" Emily asked not surprised.

"Uh huh! She also whispered some stuff to Auntie JJ that I wasn't awwowed to hear," Riley said frowning.

"Oh my god,' Emily said under her breath rolling her eyes, "Well, when you're older…" Emily said laughing and let Garcia take her away.

"Yeah when I'm dead and gone," Derek said.

'C'mon, JJ," Garcia said. JJ rolled her eyes and followed the hot pink and orange clothed lady out the door. Derek shut the door behind them.

"Alright. Let's talk," He said.

"And…just hear me out, okay?" EMily asked.

"Yeah. Alright," He agreed.

"I love Riley. And Riley needs a father. Everything I do his for Riley, but I want to be with a man I love as well. I want him to love Riley as much if not more, than I do. I want him to love me, too. I want a man that will take care of us always. And this is why-" Derek cut her off.

"Jesus, Emily, you can't take her away from me. I love her! So much," Derek started to plead.

"You didn't let me finish," Emily explained, "It hurt so much to leave. I wasn't even sure why I was leaving. All I knew was that I was pregnant with your baby and I hated you but at the same time, i loved you so much. I wanted to be with you forever. Raise our child together, and it didn't happen. I left once. I lost you once. I can't let myself lose you again," Emily said with a tear rolling down her cheek.

"Wait…so you're saying…" Derek was putting 2 and 2 together and coming out with 5.

"Derek. I. Love. You. Get it?" Emily asked.

"You do?" Derek asked excitedly.

"What'd I just say!" Emily exclaimed.

"That's good cause I love you, too!" He said. He picked Emily off her feet and kissed her passionately and she kissed him back. Then he got down on one knee.

"Derek?" Emily asked with a tear coming down her face.

"Emily Prentiss," He began and pulled a box out of his pocket, "Will you marry me?" He asked.

"Derek," Emily's jaw dropped. A few tears fell.

"Please say yes…otherwise I'm gonna look like such a jack..bringing the ring all ready to go, and then being denied…" He said laughing a little.

"Oh my god….yes!" Emily shouted excitedly. He put the beautiful diamond on her finger.

"Oh, god, Derek it's beautiful!" She said while some more tears fell.

"Not like you, though," He said laughing at that cheesy line that he meant so truly. They kissed and kissed for a long time. THen they walked out together holding hands to Riley, JJ and Garcia who were playing together.

"So what happened in there?" Garcia blurted out. Emily showed them the ring.

"Holy Crap FINALLY!" Garcia explained and almost knocked JJ over as she ran to hug Emily and then , although so excited for them, stayed a little bit more calm.

"Congratulations, hon," She said hugging Emily tightly.

"Thank you so much, Jayje, for everything," Emily whispered as they hugged.

"Always," She said and then hugged Derek.

"C'mon! Let's go tell everyone else that you're mommy and daddy are getting married!" Garcia exclaimed to Riley.

"Wait!" Riley commanded. She walked over to Emily and hugged her very tightly. Then she walked over to Derek.

"Bend down!" She comanded, so he did.

"Daddy," Riley began.

'Yes, princess?" He asked.

"I love you lots," She said and kissed his bald forehead.

"I love you lots too!" He said kissed her and hugged her.

"C'mon Auntie Pen! Let's go! Auntie JJ you come too! And mommy and daddy!" Riley squealed.

Emily and Derek watched as the three of them ran to tell everyone else. Emily smiled. They would be a family together again after all. Even after everything, they could finally love each other forever and be together. Derek put his arm around her shoulder and pulled her close.

"You, me, and Riley. Right here. Forever," Emily said wistfully.

"Forever," Derek promised.
