Here's the last chapter! Warning, there's some intimate stuff at the end. Not anything graphic, or overly sexual.

I will put a note at the end of the chapter as well. Enjoy!

Spencer woke up the next day and got ready for work as quietly as possible. JJ still slept beside him, happy and sated.

It was currently 7:30am and Spencer was exhausted, but also quite happy. The two of them had been up until half past midnight celebrating their engagement.

After getting dressed and having a cup of coffee, he went into the nursery to say goodbye to Henry before gently kissing his sleeping fiancee goodbye. He filled his travel mug with even more coffee and happily headed to work.

Everyone could tell when he strode into headquarters that he was in an extraordinarily good mood. In fact, they didn't think they had ever seen him in a better mood.

"What's got you feeling so good Pretty Boy?" Derek asked, rolling over from his desk.

Spencer sat down at his own desk and waited a couple moments before replying, as if to create more suspense for his impatient friend.

"JJ and I are engaged."

His friend smiled from ear to ear and patted him on the back, "congratulations man, I knew you had it in you! Only took several years, but you did it!"

Emily walked into the bullpen with a knowing smile, "are you two talking about the engagement?"

"How'd you know?!" Spencer asked her, as she leaned over his chair and put her arms around him in an embrace.

"JJ called last night and told us, of course!"

"I wanted to tell you guys..."

"Tell us what?" Jordan was passing by on her way to the conference room.

Apparently when Emily said us she was only referring to her and Penelope.

"JJ and I are getting married next February," Spencer told her.

Jordan congratulated him, and Derek inquired about the date, "you already know?"

"Yeah, JJ wants it to be February 7th."

Hotch and Rossi walked up to the bullpens, able to tell by the excited tone of the team that JJ had accepted Spencer's proposal.

"That's the day you were kidnapped by Hankel." Hotch remembered.

"She figured since I made November 3rd a happy day by proposing that we should do the same for that day. We're doing it next February though to 'have time to plan.' I don't know why it takes so long to plan a wedding, but apparently it does. Probably all the st-"

"Watch it Reid, there are other ladies here," Rossi warned, "women don't like being told that big weddings are stupid. Or hearing anything close to complaining for that matter. I didn't learn that until after my third."

The other men laughed, while Jordan and Emily rolled their eyes. Jordan decided to leave the team alone to celebrate and silently went up the stairs to the conference room.

"Celebration at my house tonight, right Reid?" Rossi asked, "lots of food and wine!"

"Of course! As long as we don't get called away on a case," Spencer replied happily.

"Great!" Derek exclaimed, "a place with food and wine is always a place I want to be. Hey Emily, do you want to come with me?"

She seemed surprised by his asking because of his constant flirting with Jordan, "of course, do you want to meet there or pick me up?"

Spencer smiled as he listened to his friends talk between themselves; Emily and Derek spoke about tonight's arrangements. Then Derek continued to tell her about the new Saw movie that had been released almost two weeks ago, and how he had yet to go see it.

Hotch and Rossi were talking about what type of wine to open and what exactly to make for dinner. Or whether they should just order food or take the team out to celebrate.

Eventually they all got to work, filing paperwork and hoping they didn't get called away on a case. Surprisingly, they were lucky for a second day in a row and at five o'clock they were all allowed to go home. They decided to meet at Rossi's in two hours time.

When Spencer arrived home JJ was already ready and excited to take Henry out for the first time. She had her light winter coat on, and was putting Henry into a big one with little baby gloves and a hat. He looked quite snugged up, as if it was a blizzard out.

Spencer put his stuff on the counter like he usually did before saying, "it's only raining JJ, he doesn't need all of that."

"He's a baby Spence, you know from all your research that they get sick more easily-"

"Yeah, but we're going in a heated car. He's going to melt."

JJ smiled as she put their son into his carrier, before going over to Spencer and wrapping her arms around him.

"Only a week and we're already disagreeing over our son," she kissed him gently.

When he tried to pursue the kiss further she slapped him away and laughed, "we'll be late Spence!"

He made the type of comment that would surprise the rest of the team, but no longer surprised her. Before picking up the carrier and setting their son up in the car.

They drove to Rossi's with Spencer driving slower than he usually did, between the rain and the fact that their baby was in the car.

Driving home from the hospital had seemed to take forever to JJ, whether by his driving or just her excitement she hadn't known.

"There you guys are!" Derek was the one that had answered the door, and he took the carrier from Spencer.

"How's my favorite little prodigy doing?" He asked as he started taking Henry out.

"He may not be a genius Derek!" JJ laughed.

"Don't say that, I'm hoping that he'll be even smarter. Someone has to be smarter than Reid, might as well be this guy!"

Spencer smiled and followed after Derek, who hadn't given their son back as he walked into the kitchen holding him.

Emily and Penelope were in the kitchen; Emily immediately went over to look at JJ's ring, while Penelope opted to coo at Henry and give him a stuffed animal that was larger than he was.

"You can't carry this yet, but when you can you'll love it because it's from Auntie Penny!" She had said, as the little boy looked at her happily.

Rossi's home was open concept and the other two men were seated in the living room, speaking together. Spencer joined them while the others gushed over the baby.

"They aren't even giving him enough room to breath," he said with a smile.

"That little boy's going to have a big family!" Rossi handed Spencer a glass of wine.

"Yeah, more than what I had. I'm so thankful that he – that we have all of you guys."

"Has your father spoken to you since he was born?" Hotch asked sadly.

"I wrote to him when JJ told me she was pregnant, but he didn't write back. Then I wrote to him to let him know that JJ had the baby and he wrote back saying 'Congratulations.' I imagine he was still sore about what had just happened in Vegas."

Spencer sighed and shook his head remembering how stupid he had felt.

The two men looked at him with pity, and Derek joined them with Henry still in his arms.

"Well, Henry will have a better father than you had Pretty Boy. Are you inviting him to the wedding?"

"I think I should, but whether or not he shows up is his choice."

"Do you want him to show up?" Rossi asked, and Spencer thought for a moment.

"Yes, I really do. It would mean the world to me if he showed up."

A couple moments of silence passed, before Spencer turned to Hotch, "How's Jack?"

"He's good, I visited him during the weekend and he gave me his Christmas list. I told him 'Jack, Halloween just ended.' And he said 'yeah, but what if Santa's post man gets delayed.' Apparently Haley had been complaining about something of hers being late."

"He's very smart and he can't wait to start school next year. However, he's mostly focused on whether or not 'Santa' will get him the bike he wants."

"And will he?" Derek asked and Hotch nodded and gave a rare smile.

"It's already in the garage."

At that moment Henry started fussing in Derek's arms and he gave him over to Spencer.

"The best thing about babies is that I can always give them back to who they belong to."

"One day you won't have that luxury," Rossi said.

"Never! I'm never having kids of my own, I have too much fun being a bachelor."

"Wait five or eight years Morgan, you'll change your tone," Spencer told him.

"Never! It's never going to happen-"

The four men kept talking about families and life until the three ladies joined them.

They spoke about the wedding; JJ asked Penelope to be Maid Of Honor and Emily to be a bridesmaid. While Spencer of course asked Derek to be his best man.

They spoke about wedding planning, with the ladies mostly leading the conversation. The men looking at each other awkwardly and trying to follow what was being said.

"What's the difference between a bridal shower, a bridesmaids' party and a bachelorette party?" Spencer asked timidly.

Penelope rolled her eyes, while Derek gave him a warning look, "they celebrate different things Spencer!"

"But why do men only get a bachelor party? That's not exactly fair-" He said jokingly.

"I agree with that!" Derek exclaimed, "Pretty Boy should get a grooms shower and a best man's party!"

"Men don't do that Derek," Emily said, "you just want a chance to drink and get close to women."

He sounded offended as he stood up to say, "I resent that! I think it's sexist to assume to that a groom-"

"Oh shut up Morgan," Spencer pulled him back down.

"We'll have our own parties here if Reid wants," Rossi offered with a laugh.

"Sure, which I absolutely do! Are you pacified Morgan?"

"Yeah, actually," was the short response from his Best Man before he drank more wine.

"You're an idiot Morgan," Emily was giving him a look and Derek raised a glass to her.

"Maybe, but you love me anyway!"

"She certainly does," JJ put her arm around her friend, who had turned red.

"No, I don't!" She replied in an immature, but playful tone.

"I think Morgan has had enough wine!" Hotch said as a distraction from the awkward tension in the room, which Emily was thankful for.

"I haven't! I've been holding Henry most of the time, I've only had like… two glasses."

"Wine doesn't agree with Derek Rossi, you should know that after a year with us," Spencer took his friends wine glass, "you should have given him beer… or nothing."

Derek protested this, but stopped when dinner arrived shortly afterwards. He seemed to get less excited as he happily ate the pizza and chicken wings that Rossi had ordered.

Eventually Emily's face went back to it's regular color and everybody went from talking about the wedding and the baby, back to work and the cases that they had coming up.

"Even when we're celebrating something we end up talking about our job, doesn't that make us a little disturbed?" Emily asked.

Derek, who was the one sitting beside her was the one that answered, "I don' think so, we all care about our job and that's what makes us the best team that the BAU has, if I say so myself. The seven of us are great together, and we all have our own personal reasons for being here. We chose to be here – JJ you have to come back!"

He added after the surprising monologue that had them all smiling from ear to ear.

"It has only been a week!" JJ exclaimed, "besides I thought you were happy with me leaving Derek? Because it gives you more time with Jordan. By the way, where is she?"

"She said she didn't want to intrude," Rossi answered.

"You guys should make her feel more apart of the family. She has been trying very hard-"

"Derek makes her feel plenty part of the family for all of us," Emily said, somewhat bitterly.

Everyone noticed this, except for Derek.

JJ gave Emily a look that made her feel a little guilty. After all it wasn't Jordan's fault that he was more interested in her. Despite the fact that they had been working together for almost two years now. Jordan didn't have to flirt with him so much though.

The team continued talking about the recent cases that they had solved, including the recent cases of The Blue Ridge Strangler and Mike Hicks. Spencer and JJ had to get up every once and a while to tend to Henry, and before any of them noticed it was late.

"Look at the time," Rossi exclaimed, "we come together to celebrate an engagement and we spend most of the time talking about murderers."

"That's how we celebrate Dave, haven't you gotten used to it by now?" Hotch asked with a smile.

"No Aaron, I guess I haven't. We've had very little to celebrate, aside from Henry's birth and of course, you two returning safely after what happened with Michael."

Spencer smiled, "definitely was an interesting way to start your return to the BAU, wasn't it Rossi?"

Rossi had just returned to the BAU from retirement, only a few weeks prior to Michael.

"I wanted to be of use, but none of us felt like we did much of anything. You're the one that saved JJ and yourself Reid. And you proved me wrong about you."

Spencer gave him a questioning look so the older man continued, "when I first met you I thought you were way too young to work for the BAU. You were only twenty six, and when I found out that you had already been working in the field for five years all I could think was 'what the Hell was Gideon thinking?' But I was wrong."

"We all felt that way when Pretty Boy first joined-" Derek started.

"Speak for yourself," JJ interrupted and Hotch agreed;

"I didn't have any doubts about Gideon's decision to bring Reid onto the team. I one hundred percent trusted his judgment. I knew there had to be something about him for Gideon to choose to bring a new recruit straight from the academy, with no experience."

"Well, what we thought was no experience," Hotch added as an afterthought, "if we had known that you had worked for the CIA – Well, none of us would have had any doubts."

Spencer smiled, "thanks Hotch, it means a lot to me to know that you had my back from the beginning."

He looked at Derek with a look that clearly said 'unlike you.' His friend could read this;

"I had your back Pretty Boy! I just-"

"Thought I was 'a punk kid that you didn't want to babysit around the field all day?'"

Derek sighed and everyone, but JJ and Hotch looked surprised.

"That's what you said?" Emily asked, looking between the two best friends with surprise.

Spencer was smiling while his older friend shook his head at him.

"You having an Eidetic memory may come in useful most of the time, but sometimes it's a pain in the ass. Get used to this JJ, he won't let you forget anything that you mess up!"

"Oh I know, I'll get used to it," she smiled and took a hold of his hand, "I'm with you for the rest of my life. I love you Spence."

She kissed Spencer gently and the rest of the team smiled.

Only Hotch seemed to notice the nervous look on his face when she pulled away.

Hotch found Spencer afterwards in the kitchen, having offered to clean up after their dishes since Rossi was nice enough to throw them the engagement party. It also gave him room and time to think and get his emotions under control.

"Reid, you're not going to be like him," Hotch said, coming up behind him and making him jump slightly.

Spencer didn't answer right away, as if trying to decide whether or not to pretend to be ignorant. He decided not, knowing he couldn't fool the older profiler. He turned away from the sink and leaned on the counter.

"I know, it's just being here – celebrating us getting married and talking about our jobs-"

"It's overwhelming? Makes you wonder if you can do it? We talked about this yesterday, you're better than him. Better than any of us, and no matter what happens I know that you two will work it out. There's an important difference between you and JJ and us."

Hotch was referring to himself and Rossi, and their failed marriages.

"JJ is just as dedicated to the job as you are. She understands the demands of this job, just as much as you do. That's why you two are different and that's how I know you two will be fine, no matter what happens. As for your fear of being your father, I know that-"

Spencer interrupted, "to be honest Hotch, I'm more worried about becoming my mother. I wouldn't be a good dad for Henry if I developed Schizophrenia. I wouldn't be a good husband either and JJ would leave me. The only difference would be that she'd take Henry with her."

"What's the statistic for you inheriting your mother's illness?"

"Considering the fact that I only have one parent with the disorder, about ten percent."

"That's not very high Reid," Hotch said, trying to reassure him.

Spencer sighed, "I know that, but it has always been my biggest fear, especially now that I have Henry. My mother had no business having a child and I shouldn't have been left with her. I know that I won't ever leave Henry, but the idea of losing my mind and losing them-"

They were interrupted by JJ coming into the kitchen, already wearing her coat and having put Henry in his carrier. The two men had been talking quietly so that the others couldn't hear.

"Hey Spence, are you ready to go? It's almost ten thirty, we should get Henry to bed."

He smiled at her and nodded, saying goodbye to Hotch before going into the living room to say goodbye to the others.

"See you tomorrow Pretty Boy!"

"You better bring Aspirin for him Reid, I imagine he'll need it!" Emily called, waving from beside Derek on the couch, "I'm going to drive him home."

Derek had had a couple more glasses of wine after supper, despite their discouragement.

Spencer smiled and told her that he would, while JJ made a comment about their two friends in a whisper behind him. This made him laugh and he wondered if she was right.

Penelope hugged the two goodbye and congratulated them again. Then decided to coo at Henry some more, while the two of them went to thank Rossi who had joined Hotch in the kitchen.

JJ drove them home since Spencer had had a couple glasses of wine. She hadn't had an Alcohol of course, since she was currently breastfeeding.

"What were you and Hotch talking about?" She asked.

"Just about my fears and worries."

"I hope you aren't having second thoughts already," JJ smiled and Spencer shook his head.

He grabbed her hand and kissed it, "I will never have second thoughts about you."

She beamed at this and tried to not get distracted by the romantic gesture, "I'm happy that you're opening up about your feelings. We were worried you'd shut down again."

"I probably would have, but you guys didn't let me," Spencer turned to look out of the window at the rain, still holding her hand, "I've found that it's very easy to open up to Hotch."

JJ glanced at him and still smiling said, "he seems to have almost taken Gideon's place."

"No, he hasn't," he replied with a small shake of his head, "nobody could take Gideon's place. I wish that I knew where he was so-"

Spencer fell silent, but she finished his sentence for him, "so we could invite him to the wedding?"

He didn't reply, but kept looking out the window intently as if getting lost in his thoughts. It was Henry that snapped him out of his mind, starting to fuss in his carrier.

"We're almost home Henry, then I'll give you a bottle and put you to bed."

Spencer turned slightly to reach into the backseat and gently took his son's hand. This calmed him, and the little boy's cries stopped as his father rubbed his hand gently.

When they got home JJ left him to tend to their son and went into their bedroom.

He got a bottle out of the fridge and put it into the microwave to heat it up.

"Let's get all these layers off of you," Spencer said, "your mother seemed to think that it was negative ten degrees out… oh, you're smelly too. Let's get you changed and in your sleeper."

Spencer took Henry to the nursery and put him on the changing table to change him.

After a couple minutes JJ brought the bottle from the microwave in as it had finished heating. She walked up behind him and ran her hands up his back.

"You almost done putting him to bed?" She asked, resting her chin on his shoulder.

Spencer lifted their son up and turned to her, his breath catching when he saw her.

She was wearing a silky blue nightgown that brought out the blue in her eyes. It was new and barely reached mid thigh. It was the first time since the second trimester of the pregnancy that he had seen her wearing lingerie. She was always beautiful but seeing her like this, after so long, was a surprise. A very good surprise for him and she smirked.

In the last year she had learned a lot about Spencer. And she loved the dumb look that only she could put on his face. It was this look that her genius fiancee was wearing now.

He took the bottle out of her hand and sat down in the chair with Henry.

"Come on Henry, after you finish your bottle it's bedtime. We want to go to bed too."

JJ left the nursery and returned to their bedroom to wait for Spencer.

Once their son was asleep he went into their bedroom quietly, expecting her to have fallen asleep but hoping that she hadn't.

Spencer walked up to the bed on the side that JJ was laying on. She heard him come in and moved to her knees, facing him as he stood beside the bed. She wrapped her arms around him and kissed him passionately.

"I've missed you," JJ told him in between breaths.

He wrapped his arms around her and pulled her closer. Eventually she pulled him down onto the bed and they laid together for a few minutes quietly, trying to catch their breath.

"I love you Jennifer Jareau," Spencer said, brushing her hair behind her ear, "I can't wait to marry you."

She smiled, "and I can't wait to be your wife."

He kissed her and she sighed happily, "fifteen months can't come fast enough."

She moved to straddle him and started unbuttoning his shirt, "people rehearse their weddings, right? I think we should rehearse our wedding night."

Spencer put his hands on her hips, "are you sure? Aren't we supposed to wait six weeks before doing this?"

JJ thought for a moment as she ran her hands over his chest, "we have to wait to have 'intercourse' for six weeks, that's what Doctor Tran said. She didn't say that we couldn't do everything else."

She kissed him again before he got a chance to rely, continuing to run her hands over his chest.

They laid beside each other later, smiling with their arms around each other.

JJ pulled the comforter over her, and snuggled closer to Spencer, "that was amazing."

"That doesn't even cut it," he wrapped his arm around her waist and pulled her even closer, "I missed this."

She laid one of her hands on his chest and closed her eyes, completely content and feeling extraordinarily happy.

"I love you Jennifer Jareau."

He could feel her smile against his chest, "I love you too Doctor / Agent Spencer Reid. I can't wait to marry you."

"I actually agree with you," he said, "I'm excited for our wedding day, just not the planning of it."

"|I'm so happy that we're together and that you're safe and we have Henry – Look at me, getting all sentimental and cliché-"

JJ put her finger on his lips, "I love you Spence, I will always love you. We're safe because of you, and I don't care if you're a genius, a special agent or a CIA agent – I never cared about that. I just wanted you to trust us, especially me. I just wanted you to come home, and you did."

She kissed him softly, and before deepening the kiss she said, "you're nothing more or less to me than Spencer Reid, the man that I'm going to love with my whole heart, for the rest of my life."

He smiled into the kiss, "I will always love you too. You're the one that saved me too, you know that right? I wouldn't have come home if it wasn't for you. You're the one that I couldn't bear leaving – Running away wasn't an option anymore. That's why I came back, for you JJ."

She felt like crying, but it wasn't tears of sadness or pain. Rather, tears of joy and the sentimental words got to her. She laid back on his chest and pulled his arm around her shoulders, kissing his hand.

"February 7th, how many days is that?"

Spencer only thought for a moment before answering, "four hundred and sixty days."

"How much do you think can happen between now and then?"

"Tons, especially with this job, but you and I will get through anything together."

"No running?" JJ asked, looking up at him with a smile.

Spencer kissed the top of her head, "no more running. I'm not leaving you and Henry, no matter what."
