The son's name is Maximilian, meaning "greatest", because in my opinion of course Spencer would name any offspring of his with high praise in mind.
Also, as a gift for not including smut in this one, I tried my hand at writing in that coveted second person. Enjoy!
It was nearly sunset when you found a parking spot right next to the federal building but the toddler bouncing in the back seat was far from ready for bedtime. You hummed a lively tune and slipped the boy a quick kiss as you got him out of the car and traipsed into the building, diaper bag and juice boxes left strewn in the front seat.
"Mama, go!"
"I know, baby," you replied with a smile as you steered him toward the front desk, "we're going!"
You checked in and snapped a visitor badge to the front of your shirt and one to the back of little Max's and he bid an excited goodbye to the secretary before the both of you headed for the elevator. The pattering of his feet came to a stop as the doors slid shut and he looked up expectantly at you, a look you loved and knew well and that was quite reminiscent of his father.
"Can you push the number six button for me, love?"
It only took him a few moments to locate the correct number and he was hopping around in excitement even as you rode up floor after floor, making sure to tap every edge of the FBI logo emblazoned on the floor.
"Maximilian," you warned, "let's make sure we still have some jumping left for when we see daddy!"
"Ok! See daddy!"
The child finally came to rest as the doors slid open again and his tugging at your shirt had you scooping him up. You recognized a familiar face standing at the double glass doors and called breezily to the man.
"Hey Kevin, how are you?"
He pushed his glasses up to see you better. "Oh, hi Mrs. Reid! Still weird to say that…but good to see you!"
You laughed and patted Kevin's shoulder in thanks as he held the door open and you strode into the bullpen. Max on your hip had become quiet as he took in the massive room and he cooed as his hand drifted on a filing cabinet you passed. The only two people currently in the bullpen were leaned on one of the desks and they looked up at the noise. Penelope let out a squeal and scurried toward you with a smiling Derek in tow.
"Max-a-million-bucks! How are you?"
"Gigi!" Max piped up.
The blonde beamed at him. "Yeah, it's Gigi! Oh my god, he's so smart and lovely and I just wanna frame him just like that for forever."
"Seriously, look how handsome the little guy is," Derek touched a gentle hand to Max's wild brown curls and his striped cardigan that look suspiciously like one Spencer had worn earlier in the week. "I won't even have to teach him how to charm!"
Your smile shone as she pressed each agent into a hug. "Both of you are too sweet and it's so good to see you again!"
Penelope held out her hands and Max excitedly leaned over to her and she immediately began bouncing him around. Looking back at you, she sighed and twisted a hand in your baggy sweatpants. "How do you do it? You're radiant even when cosplaying the Michelin man. And you know I'm so incredibly happy to see the both of you but to what magnificent occasion do we owe the pleasure of this visit?"
"Yeah," Derek added, "what brought Missus Genius and Jr. to us this late? Reid's filing a report, by the way, I'm sure he'll be right down."
You stretched your neck and stifled a yawn as the length of the day started to hit you. "Since Spencer was away for a bit longer on this case we to my parents' for a few days, and heading home today Max said he couldn't wait to see daddy any longer. My hometown is a long drive away and that plus a toddler made me decide against my frock and gloves for traveling." You gave Penelope a teasing wink before asking, "Anybody else here I can say hey to?"
"Nope, it's just me and my chocolate thunder and your dearly beloved left here this late. Even head Hotch-o headed home. Ooh, alliteration for the win!"
A voice from the back of the room spoke up. "Hey, shouldn't I be the one to teach my kid alliteration?"
Max's head snapped around and he wriggled out of Penelope's grasp with a war cry. "Daddy!"
He thundered over to where Spencer was knelt down and wrapped him in as big a hug as his little arms would allow. Spencer nestled his face in the boy's neck as he lifted him and headed back across the room, father and son exchanging whispered "I love you's" and "I missed you's" all the way.
Penelope turned to you with a blinding smile. "I'm going to melt into the basement because of your boys, this is one of those magical moments you can only dream of! Is Max already like one of those super mastermind kids?"
You laughed and held her outstretched hands. "Well he's a least a bit ahead of the curve. We hit eighteen months a few weeks ago and there's already plenty of coloring inside the lines and a confirmed vocabulary of twenty-one words."
"You hear that, prettyboy?" Derek asked Spencer as he finally reached your trio. "Looks like little man has the brains to take over your job soon."
"Most of which I think he gets from his mother," Spencer countered, his fond gaze rested solidly on you.
Penelope looked frantically back and forth between the two of you as nothing happened for a few moments. "You can kiss your bride, boy wonder, Derek and I have seen grown-up movies before."
Spencer accepted the encouragement and shifted Max to his left as he leaned in to hold your cheek and press a swift kiss to your lips. His delightful mouth was as soft as you'd remembered and you snuck in one more kiss before he pulled away.
"I love and missed you, too," he murmured and wrapped you in a hug.
It was Max's giggles and shoving that finally parted you and Spencer's free hand came to yours as you said, "Right back at ya. You ready to head home?"
"More than ever."
You fished out your keys and shouldered your husband's messenger bag as Penelope and Derek bid loving goodbyes with hugs and kisses and demands to see your little family soon.
"Can you say bye to them, Max?" you prompted your darling son still nestled in Spencer's arm.
He thought a moment before his hand waved enthusiastically. "Bye Gigi! Bye Unca Mogan!"
Penelope probably would've fainted if Derek didn't have an arm crushed around her and the pair waved back as your trio departed. Spencer was determined to be hands-on now that he could for the first time in days, so he was the one to buckle Max in and make sure he had a snack and kept the little one chatting for the whole drive home.
As you pulled into the driveway of your cozy house Max got fussy with how dark it was and Spencer was quick to retrieve him, making sure to press a kiss to his temple and yours as you made your way inside.
Shirt and cardigan now askew, Max was mumbling and rubbing his face as you turned on warm lights around the house and Spencer softly laughed at him, carting the boy away to get ready for bedtime. You peeked your head in the brightly decorated bedroom just as he was getting tucked in.
Max was still sitting up and reached his hands over to Spencer's eyes. "Eyes, daddy!"
"Yeah, buddy, those are my eyes!"
"Eye, eye…" Max trailed off before another thought struck him. "Einstein!"
Spencer sat back as you gazed at them in disbelief and your joyous gasp rang out. "That's my smart boy!" You ran to wrap him in another hug and kiss before turning back to Spencer. "So that's a confirmed twenty-second word?"
His eyes were sparkling with pride. "Definitely, and the most complex so far."
You finally got the little one tucked in after a quick bedtime story and he was peacefully snoozing by the time you and Spencer crept out of the bedroom. You shared another loving kiss and a few other pleasantries as you both unpacked and washed up from the long day.
It was when you were back in the kitchen and Spencer was washing a few leftover dishes in the sink that he said, "I still can't believe he said Einstein."
You looked up from where you were hunkered over your planner on the island. "Yeah, that was pretty incredible. Wonder where he got that from, hm?"
The two of you laughed and Spencer dipped his head modestly, a quirk you couldn't get enough of. You studied him a moment longer and then decided it was time. You poignantly continued, "We'll have a whole army of little geniuses with all your talk."
"Just an army of one for now," he mused.
Bringing a hand to your belly, you cleared your throat so he would be sure to hear you. "It'll be more than one sooner than you think, Spence."
Even his brilliant mind took a moment to process your words but as soon as it did he spun around wide-eyed. "What are you saying?"
"I'm saying that I noticed morning sickness the first day I was at my parents' and so I took the test and retook it twice and I wanted to wait until we were face-to-face to tell you it was positive all three times."
Spencer had been slowly moving toward you the whole time, enraptured with your glowing features, and his voice was barely above a whisper as he let his knuckles come to rest on your cheeks. "We're having another baby?"
"Without a doubt," you kissed his frozen features, "baby Reid #2 is on the way."
His throat bobbed as he fought back tears and he gripped you into a hug almost too tight. "You're amazing."
You hugged him back and the two of you stayed that way for moment after blissful moment, drinking every bit of tenderness in. When you finally pulled back, you teased, "While I may be amazing, do remember it takes two to tango, Mr. Reid."
The blush on his cheeks was brighter than the red shirt rested over your little growing creation.
