A/N~ Takes places during season 3, episode 6, 'About Face'.

Ariel's P.O.V.

Spencer called me around ten in the morning on Halloween, completely freaking out.

"Ariel, he's here!"

I laughed as I opened up the fridge, seeing what was in it. "Or hello, as people used to say."

"Hi." he amended, but then continued with his freak-out. "But Ariel, it's him! Its David Rossi! The David Rossi!"

"Oh killer," I mused as I pulled out a carton of eggs. I didn't really get all that hungry anymore, but I knew that I had to eat something - if not for me, then for the baby. "You didn't scare him, did you?"

Even through the phone I could tell that he had straightened up. "I don't know what you're talking about." he said calmly.

I snorted. "Yes you do." I argued. "You went off on a babble-fest as soon as you were introduced, didn't you?"

His silence was all the answer I needed.

"It's alright, sweetie." I told him, laughing. "You wouldn't be you if you didn't."

"How's the baby?" he asked, and I scowled, even though I knew he wouldn't be able to see it.

"Your child is currently using my bladder as their own personal punching bag." I grumbled. "I honestly cannot wait for this baby to get out."

"Why is it my baby when its annoying you?" he complained, and I couldn't help but smirk.

"Do you really need me to explain that to you again?" I teased, and he laughed softly.

"There's still another few weeks left, Ari-bear." Spence said softly. "You know that."

"Oh, I'm perfectly aware, Spencer." I said, snapping slightly. "But a girl can dream."

"We have a new case." he told me, and I sighed.

"Alright." I said. "We'll just have to have the Halloween party when you guys get back." I pulled out a frying pan and adjusted the phone so that I could hold it between my shoulder and my ear - that way we could continue talking while I made my food. We talked for a little while longer about random things before Spence said that he had to go.

"Fine." I said, smiling softly. "But be careful. And keep your phone on - maybe we'll get lucky and the baby will come early."

"I will." he promised. He was about to hang up when I called out again.

"And Spencer?"

"Yes?"

"Invite Agent Rossi to the party." I told him. "It'll be a nice way to welcome him to the family."

Rossi's P.O.V.

We were back in Quantico, and I watched the rest of the team for a moment before following Hotch back up to his office.

"You said out there," I began slowly. "The team shares everything." Hotch turned around to look at me, getting up from behind his desk at the same time.

"That's right." he replied.

"There is no… 'I'?" I asked, and he nodded, looking confused. He was most likely wondering where I was going with my questions. I walked a bit further into his office before I said anything else. "Seems a big thing to withhold… separating from your wife, your child."

"What are you talking about?" he asked me, but the expression on his face said that he already knew.

"You used to call Haley ten times a day. We've been together forty-eight hours, I haven't seen you call her once. Haven't heard you mention her."

"What's your point?" he asked, but I continued with what I was saying, pulling out another piece of information that I had noticed during the short case.

"Hell, I've seen Dr. Reid on the phone at least three times a day, and I could hear him talking through the night through the wall of my hotel room." I told Aaron, who smiled slightly. "Maybe he's got secrets of his own."

Just then, the kid himself came bursting through the door to Hotch's office, looking like someone had just dumped an entire bowl full of candy in his hands.

"Hotch, the Halloween party's canceled." he said quickly, giving us both an awkward smile. "But we're meeting up at the hospital instead, okay?" he asked, and then nodded as if we had answered him before running out again, yelling to Morgan as he raced down the stairs, "Have you seen my jacket?"

Hotch got up quickly and ran over to the door. "Reid!" he called out, getting the young genius to stop for a minute. "Why are we meeting at the hospital?"

The question seemed to get him to stop and breathe for a second, although it could have had something to do with the calming effect that Hotch had on people in general. Whichever it was, it was enough to get the kid to slow down.

"It's time." he said as he grinned like a loon, pausing by the doors long enough to talk to us. "Kat just called - called me from the hospital. The baby's coming, Hotch." Then he started to freak out again. "Oh my god, the baby's coming!"

Hotch smiled at that, while I was dumbstruck. He said something else before coming back into his office, while Reid went flying out of the bullpen with Morgan hot on his heels. Garcia, JJ, and Prentiss weren't far behind.

Hotch was grinning when he turned around. "Dave, are you coming?" he asked me.

"Hold on just a second." I said, and he froze, his stern mask settling back into place.

"What is it?"

"Baby? What baby?" I asked, and he visibly relaxed, smiling slightly.

"I forgot that you've literally just joined the team." he said. "Ariel, Reid's wife, apparently just went into labour. They've both been freaking out about being parents for the longest time now." he started to head out the door then. "Come on, it'll be a great chance for you to meet her - you'll get a kick out of her, trust me."

I was still in shock, but followed Hotch anyway. "Why?" I asked, confused, although he didn't answer. I was still having a hard time coming to terms with the fact that Dr. Reid was married - although I had noticed the ring on his finger, it just hadn't connected in my mind. But now, I was picturing Reid's wife as a - pregnant - tiny, demure woman who was very similar to him.

Needless to say, I was surprised by how wrong I was.

Five minutes earlier…

Spencer's P.O.V.

I just put down my messenger bag when I saw the message light on the phone on my desk blinking red, but just before I could start to listen to them, the phone rang again.

"Someone's popular." Morgan joked. I just rolled my eyes and picked up the phone.

"This is Dr. Reid." I said, and then had to hold the phone away from my ear due to the unearthly screech that came from it.

"WHERE THE HELL HAVE YOU BEEN?" Kat screamed.

I stared at the receiver for a moment before putting it back to my ear. "I've been on a case." I said. "Why, what's happened? Is Ariel alright?" At that point both Morgan and Prentiss were looking at me, their curiosity clearly written on their faces.

"Oh, nothing much." Kat replied, sounding a lot calmer. "She's fine, just in labor."

"Okay, so why are you calling me in a screaming panic?" I asked her, irritated. She didn't answer. It only took a few seconds for me to realize what she said, and when I did, I dropped the phone. Morgan started laughing, but I didn't care. I scrambled to pick it back up, practically shouting,

"She's what?"

"She's in labor, g-man." she said, still sounding irritated. "Has been for the past few hours. I've been calling you the whole damn time, both your cell and your work!"

I was scrambling at that point, trying to grab all of my stuff while staying on the phone. "I'm sorry, so sorry, my cell phone died and we just got back, I'll be there as soon as I can!" Then I just threw the phone down, grabbing my bag.

"Kid, calm down." Morgan said, grabbing my shoulder. "What's going on?"

"I can't calm down Morgan!" I cried out, still panicking. "My wife is in labor, and I'm missing it!"

Rossi's P.O.V.

Hotch and I got stuck in traffic, so we got to the hospital about half an hour after the rest of the team did. The whole team was there, along with four other people that I didn't recognize. The guys - Morgan and the three men that I didn't recognize - were all laughing, and the ladies looked like they were trying their hardest to keep from joining in. Except for the one with the crazy hair, who was laughing so hard that there were tears streaming down her face.

"Is the baby here yet?" Hotch asked as soon as we were close enough. The new woman shook her head, while giving me a Look at the same time.

"No, she's been in labor for about ten hours now." she said. "I kept calling Spencer, but it kept going straight to voicemail - apparently his phone died on him and the genius didn't think to charge it." then she turned to look at me. "Who're you?"

For a moment, I was actually a little afraid of the petite woman in front of me. She definitely looked strange with her pale blue hair and tattooed body - especially with the get-up she had on. She was wearing a tight black outfit, with furry cat ears and a tail, and I was about to ask about that before I remembered that Dr. Reid had said something about a Halloween party when he came running into Hotch's office. I was wondering how on earth she knew Dr. Reid - I assumed that that was why she was here, along with the other men, because they were either family or friends of the family. But she didn't appear to be the type that Dr. Reid would associate with.

However, I reminded myself as Technical Analyst Penelope Garcia came into view, I realized that not everyone was what they appeared to be.

"I'm David." I said, holding out a hand to her. "David Rossi. I just joined the team." I explained as we shook hands.

"Rejoined." Hotch corrected, and the woman looked at him in surprise. "Dave was one of the founding members of the BAU."

She finally smiled at me then, and she looked a lot less intimidating. "I'm Katerina." she introduced. "You're the book-writer guy, aren't you?" she asked, and I laughed at that.

"I don't think anyone else has put it like that before, but yes I am." I said.

She smirked. "I bet Spencer was thrilled - did he start babbling?" she asked.

I nodded, and then looked around. "Speaking of Dr. Reid, where is he? I thought he would've been out here with us."

One of the men laughed. He was tall, with dark shaggy hair and an easygoing disposition. "Nah, man." he said. "He's in there with Ariel getting his ass handed to him."

Hotch started to laugh - to actually laugh - at that, but I was confused. "I don't understand…"

"Just wait a minute or two, Rossi." Agent Morgan said, and while he had obviously been laughing only minutes earlier, I could see the obvious worry in his face, which made sense. From what I had seen just during the last case, it was obvious that Morgan and Reid were very close.

"Why?" I asked. None of them even got a chance to answer my question, though.

It was muffled slightly by the doors, but I could make out the pained screams of a woman, followed by a voice screaming, "I SWEAR TO EVERY GOD AND GODDESS OUT THERE, SPENCER I AM GOING TO KILL YOU AND YOUR STUPID FACE!" She continued on like that, but I couldn't hear her over the laughter that was coming from the guys.

I must've looked as concerned as I felt, because JJ came over to me. "Don't worry, Rossi." she said, although she was trying to hide a smirk as well. "She probably won't carry through with her threats. Probably."

Even Hotch was laughing at that point. "I remember how awful Haley was when she was in labor with Jack. She kept threatening to do horrible things to me."

There was another round of screamed threats, and this time the other girls started to laugh as well - although their laughter had less to do with what was being screamed and more to do with the guys, who had all gone pale as they heard the threats.

"It's gonna be a long night." one of the men - I think he was introduced as Gabe - said, settling down into a chair.

No One's P.O.V.

It was about four in the morning when Spencer came out of the delivery room. He was still wearing scrubs and looked exhausted, but had the biggest smile possible plastered on his face.

The rest of their family was sitting in the waiting room, almost asleep. Kat was the first one out of her chair, and Gabe fell over as his pillow - also known as Kat's shoulder - moved out from under him.

"Is she okay?" Kat asked eagerly, looking like she was about to bust down the doors of the delivery room to see her niece or nephew.

Spencer was smiling so widely that it looked like his face was going to crack into two. "She's fine… she's absolutely perfect. So is the baby… of course the baby's perfect, I mean…" he was rambling at that point.

"Calm down, Spence." JJ said, trying to get the new father to take a deep breath.

"Boy or girl?" Garcia asked, having finally woken up from where she had fallen asleep against Morgan.

Spencer smiled at them, his eyes twinkling. "Come and see." he offered, leading us through the hallways until he opened up a door that led to his wife and newborn child.
