Hey everyone, here is the LAST chapter for you all. I hope you all enjoy this chapter. I've absolutely loved writing this and it was wonderful to do as my first AU fic. You are all the most amazing readers in the world, I see new readers every day and love the support of long-term readers. I don't know what I'd do without you all and you all deserve an award for being such amazing people.

Regarding the choice of fanfics, after going through all the reviews, I don't want to disappoint you all. I've chosen. I'm going to do BOTH! A lot of you want number one and a lot want number two so I've decided to write both of them.

Option number one's title is Quarantine. A title I'd like to thank Jael. Race .1 for. When you said you voted for Quarantine and used just that word, it just clicked and I knew it was the title, so thank you. This will get updated everyday.

Option number two's title has not yet been chosen. I'm open to suggestions and the best will get used as the title. This will get updated every two days, I hope that is okay.

Thank you all so much for the reviews, you're wonderful and I'm so happy you liked the story he told to the baby. That was the part I was most nervous about. You're spectacular and I love you all. Thank you!

Enjoy and please review

All mistakes are my own

Spencer watched as his father and family began giving the profile to the team involved with the case. He watched as everyone in his department paid attention, listening and learning. He loved how his father commanded attention in the room. They were looking for a man in their mid 20's, with a history of abuse in his childhood, the unsub would have some medical training and most likely, went to medical school, but dropped out. Looking at the case, Spencer knew it was a rough one. The victims were all female, each subjected to a horrible beating before having each of their organs removed. They had all died during being operated on. They were still alive during it all.

He looked to the board and focused on the trademark of each victim. Each had a symbol carved into one of their shoulders. A circle with three inner circles inside, different in size. It looked familiar but he couldn't recognise it. He got up from the desk and walked out of the room, aware that he received a few glances as he left. A headache was beginning to form in his head. He stood in the hall and rubbed his head.

"Spencer, what's wrong?"

He turned around and found his father behind him. "Nothing is wrong. I'm just getting a little headache."

"You aren't telling me everything."

"That symbol looks familiar but I don't where it is from. It's there but I can't recall it."

"I remember when this used to happen when you were younger. You've got so much rattling in that brain of yours, I'm not surprised that some of it's tucked away, beyond a quick recall. You've got a lot on your mind with this case. Look, call Maeve and then speak to the baby, hear him gurgle and listen to the sound he makes when he hears your voice. You need moments of happiness to open your mind."

"I've got work to do."

"You are working. Go and do what I said."

"Okay," Spencer smiled. "Just because you're an FBI agent, doesn't mean you can boss a detective around."

"This isn't me as an FBI agent, this is me, as your father."

Spencer sat outside his department and dialled Maeve's number, she was working from home and looking after the baby. He waited for an answer. "Hey, Spencer."

"Hey, Maeve," he smiled. Just hearing his wife's voice made him smile. The horrors of the crime scene photos leaving his mind. "I just called to check up on the baby and you."

"We're fine," she giggled down the phone. "You've always worried too much. Mommy and baby are doing fine. Aaron has eaten his food like a good boy."

"Can you put the phone to his ear? I'd like to talk to him."

"Sure, sweetie."

He listened as she placed the phone to Aaron's ear. He heard his son make happy noises down the phone.

"Hey, Aaron. It's Dada. I hope you're being a good boy for mommy."

He laughed as he listened to his son become excited at hearing his voice. He remembered his own mother as he listened to Aaron. His mother, on her good days, would read to him.

His mind sparked as the symbol and its meaning came forward.

Spencer rushed into the station after saying goodbye to his son and goodbye to Maeve. He rushed over to his father and his family. "I know what it is."

"What does the symbol mean?" Hotch asked.

"It's a rotation of the elements symbol," he said. "I couldn't remember it before but I did what you said. My mother would read to me from different books. She taught fifteenth century literature but we would also discuss other books, including medieval, fifteenth century alchemy. The symbol is a rough version of a rotation of elements symbol. Alchemy consists of changing metals from one to another, a richer metal and other things. Part of it is also about extending life and longevity. I think, he is practicing some twisted version of alchemy. I'd guess that his killings were recently triggered by a personal loss and his need not to lose anyone else. This symbol is in a book and the book isn't easily available."

"I'll have Garcia get a list," Emily said.

Spencer sat at the bar with his father and everyone else. They had managed to capture the unsub after Garcia had cross referenced purchases of the book. One had gotten purchased by the mother of the unsub. The unsub's name, Jared Brooks. His mother had brought the book at auction six years ago but had died three weeks before the killings had started. Jared had dropped out of medical school, where he'd had ambitions of becoming a surgeon. He was psychologically disturbed. He'd been abused by his father up until the age of thirteen. They had saved a young woman from being killed but she would need, at least, a week in hospital.

"To Spencer, who broke the case," JJ said. Everyone clinked their glasses.

"To Spencer!"

They were all drinking soda, knowing that Spencer didn't like watching people drink alcohol. Even Rossi had chosen a lemon and lime soda.

"I'm proud of you, Spencer," Hotch said.

"You did all the work, I didn't help that much," Spencer shrugged.

"Stop being a modest macho," Morgan chuckled. "Without you solving the symbol, we'd have never found the unsub in time to save that woman. You deserve the credit on this case. Even Detective Harris agrees with us on that. You were always meant to go into law enforcement, kid."

"It was great working with you all," Spencer smiled.

"We enjoyed working with you all too," Emily grinned.

Four months later

Spencer walked forward with Maeve behind him, her hands over his eyes. He'd been blindfolded in the car and didn't know where he was. He already had an idea of what was going on. Garcia had been babysitting Aaron all night, giving him and Maeve some time together. They stopped and Maeve took her hands away.

"Happy birthday!" they all called in front of him. Jenny, who had turned eight, two weeks ago, pulled party poppers with Jack and Jaime. He smiled as Maeve came next to him and kissed his cheek.

"Happy birthday, honey."

A few hours later

Spencer found himself amazed at the party, he doubted he'd ever forget turning twenty-seven. He held Aaron, who had only turned one the week before, on his hip. He put a bit of frosting from his cake on a plastic fork and fed it to his son. "I know, it's good," Spencer chuckled as he watched Aaron smile and lick the rest of the frosting off his lips.

"Are you sneaking him more frosting?" Garcia said behind him. He turned around and shrugged.

"How could I deny that face?" Spencer said, looking down at Aaron.

Garcia walked forward and brought Aaron into her arms. "I can never say no to his face."

"You guys didn't need to do all this," he said as he looked around at the party. Jamie, Henry and Jack were laughing together, all three had become good friends since they met. Jenny and her three-year old sister, Emily, were kicking around a soccer ball with Morgan, Emily and JJ. Rossi and Gideon were talking together. Hotch, Cathy and Maeve were in the kitchen, cleaning up.

"Nonsense," Garcia rolled her eyes. "We love celebrating birthdays and your birthday is one that we have to celebrate. You've come so far, sweetie. We're all so proud of you. You've worked so hard to get where you are and I knew, from the first time I saw Hotch with you, that you were going to become a member of this family. I love you, Spencer. No matter how big you get, you'll always be my nephew."

"I love you too," he said, coming forward and hugging her. "You've always been awesome, Aunt Garcia."

"You make me feel old when you call me aunt Garcia," she laughed, bringing her free arm around him. They both laughed when Aaron, placed his small arms up to join the hug.

"Dada," he smiled, tugging at Spencer's shirt.

"Don't worry, little man," Spencer said, coming away from the hug. He brought Aaron back into his arms. "I'll always be your Dada."

Sitting at the table, eating the meal in front of him. He looked around and knew he had to say something. The kids had all gone inside, Aaron was now down for a nap, little Emily was also napping too. Jenny had gone inside too and was now watching television with Jack, Jaime and Henry. Thor, had also curled up with Jenny on the couch. He was happy that they had gone inside because what he was about to say, some of it, he didn't want them to hear.

He got up and tapped his glass. Everyone went quiet, allowing him to talk.

"I just need to say something," he began. "Thank you so much for today, for celebrating my twenty-seventh birthday. A long time ago, I never thought I'd see this birthday. Today, I just didn't want to thank you all for my birthday. I wanted to thank you all for saving me when I was younger, especially you, dad."

He watched his dad look at him. "I know I did a very stupid thing once, and you saved me. I can never stop thanking you for giving me this life. One of happiness and one, I never thought I'd ever have. You adopted me and brought me into this wonderful family. One, where I have aunts and uncles who support me and wonderful god-children too. Without you, dad, I never would have survived that night I did something stupid. I never would have met Maeve, or had my beautiful baby boy. You've raised me to become a strong person and you helped me forget my past because, you gave me a new future."

He paused for a moment and watched as his father's eyes began to water, along with most of the family. Garcia was already wiping tears from her cheeks.

"I love you all so much," he said, wiping away a tear of his own. "You've given me everything. Support, happiness, family and love. Things I never had before I met you. So, I just wanted to say thank you for everything. I love you all and you'll always be my family."

He watched his father rise up and come over to him. His father hugged him tight. He hugged him back. They came away from each other. Hotch smiled at Spencer. "We all love you too and I'll always be your father. Happy birthday, son."

"Thanks," Spencer said.

Maeve kept next to him and held his hand. This was the perfect time to tell everyone.

"I have one more thing I'd like to say," he said before looking at his father. "I hope you're ready for another grandchild, dad. Maeve's two months pregnant."

"What?!" Hotch gasped with joy. Everyone at the table clapped their hands. "Congratulations, son. I can't wait to see my new grandchild."

Garcia rushed in and hugged Spencer, and then Maeve. "Oh, I'm so happy for you both."

Spencer looked around and felt happier than ever. This was his family and he belonged here.

Spencer carried his son to bed, putting him in the crib and making sure he was warm. "Sleep tight, son. Hope you're ready to get a little brother or sister in seven months. Love you, Aaron."

He walked out of the room. He went into his bedroom to find Maeve next to the music player. She pressed play. Nina Simone's I'm feeling good, began to play gently. She came over and took his hands. He held her close and they began to dance to the music. He loved the feel of her hair on his chin and the touch of her hands around his waist. He twirled her, causing her to giggle. When he brought her back into his arms, he kissed her gently.

"I love you so much, Maeve," he sighed happily. "I don't know what I'd do without you."

"I love you too, Spencer," she said, leaning against his chest and smiling. "You have such a strong heart. Happy birthday, sweetie. Did you like your gift?"

"I did," he smiled at her as she came away from his chest. "You and our children, are the best gifts in the world to me."

She leaned against his chest and they continued to dance. He had all the things he never thought he'd ever have. A wonderful family, a loving wife, a beautiful son, another beautiful child on the way and a job that helped him protect those he loved.

His family had given him life and he wasn't going to waste a second of it.
