wait your new hotch blurb got me thinking what about they got secretly married and everyone knows that hotch is married they just don’t know it’s to bau!reader because he seemed very genuine in the wanting privacy so (after complaining) they respected that, and maybe one of the team members sees hotch and bau!reader kissing in the hallway of a hotel or something and confront him about cheating on his wife

"How could you cheat on your wife?"

Penelope's harsh, degrading accusation hits Aaron directly in the chest, through the layers of stoicism that he's come to forge over the years of working in criminal investigation and straight to his heart.

All Hotch can manage is a, "What?", and Penelope's eyes dim further.

"Don't do that, Hotch. I saw you. I saw you and Y/N kissing in your office. How could you do that to your wife?"

She looks so crestfallen that Aaron's chest actually aches, so unprepared to see the famously bubbly Penelope Garcia close to tears. Close to tears because of him, no less.

Aaron might have chosen his words more carefully if he hadn't been so startled by Penelope's unusual devastation, but his jumbled brain forgoes its job and his mouth takes over, uttering the thoughtless statement, "That's- that's what she's there for."

And in his mind, it's true, if not the complete truth. You are there for him to kiss, you're there to be kissed and loved and appreciated and cherished, but he's momentarily forgotten that Penelope doesn't know that you and his mystery wife are the same person, and his words so easily warp into possessiveness and disregard.

Her face contorts into a mixture of disgust and rage that could take out a serial killer, and he seriously considers recruiting her as Chief Lecturer of the BAU, "Hotch? How- how could you say that? That your wife is just- just some thing to wait on you while you run off with someone else? You- Aaron, I can't believe you, I thought you were better than that!"

She tries storming away, tears budding in her eyes but Aaron catches her elbow, ignoring the way she flails and squirms at his touch.

"Let go of me!" She tearily demands, but he grabs her by the other arm now, holding both of her shoulders.

"No, Penelope, listen-" He tries, reminding himself to send her to Derek later for a self-defense lesson, because the weak shoves that she's pushing at his chest with do very little.

"No! No, I'm tired of listening to men," She shrieks, "You were supposed to be better than that, Aaron! I trusted you, you were supposed to be the kind of man that I could admire, and- but you're not! You're just like the rest of them, you're some egotistical, possessive, heavy-handed, domineering son of a-!"

"Y/N is my wife." Aaron cuts her off, his voice slightly raised, but not harsh. Never harsh, not to the sniffling mess of ruffles and glitter in his arms that handed him her resume on pink stationary all those years ago.

She falls silent, finally, but her lips still tremble. Aaron squeezes her arms tighter, not rough but comforting, "Y/N is my wife. We married privately late last year. We kept it secret for safety reasons, but I'll admit we didn't need to hide it from all of you. I was not cheating on my wife, I would never-" He thinks momentarily of Haley, of the gut-wrenching sound of her cell phone ringing with a call she wasn't brave enough to answer in front of him, "I would never do that to Y/N."

It's a lot of new information to process, and Aaron grants Penelope all the time she needs to work through it. When her red-stained lips part again she breathes, "You married Y/N?"

"I did." Aaron nods, and though it's not the time to smile, he can't help that a ghostly one flits over his features at the mere thought of the day he'd married you, "I'll show you pictures when we're done here. Penelope, you can trust me. I don't blame you for accusing me- in fact, I'm glad that you did. I'm glad that your loyalty isn't blind. But Y/N is my wife, and that's why I kissed her."

A very wobbly, "Oh." Is all that Penelope can manage, and she sniffles again, staring at his tie rather than his face as he holds her steady in the hallway. He's glad that they've both shown up early for the day, but you're due to return with coffee for the three of you any minute now, and he offers her his pocket square to wipe beneath her eyes.

"You said-" She chokes out sheepishly, voice unsteady as she smears the tears off of her cheeks, "You said you have pictures?"

That's how you find them when you return, seated on the couch in his office peering down at his phone. You have to set the tray you'd been carrying down on Aaron's desktop before you can properly greet either of them, but you're immediately alarmed by the tears streaked over Garcia's cheeks when she stands to face you.

"You-" She starts, not giving you a second to speak, "-are a rat! You got married," She gushes, and Aaron chuckles deeply from beside her, standing and pocketing his phone.

"You got married to our boss, and you told me nothing," She hisses, but slumps so easily into your chest for a hug that you're more than willing to give her.

"I'm sorry, Penny," You gush, squeezing her tight, "We just- we were worried about safety. The more people we told, the more dangerous it would become, so we didn't share it with anyone. But- but we should have told the team, I know."

She sniffles and you draw back to pick up her drink from behind you, sugary and pink and topped with a thick layer of whipped cream, "I got you a drink. Forgive me?"

"Reluctantly," She tries scowling, but she's never been very good at it. She takes the drink from you huffily, jamming the straw inside and taking a drag at the thick liquid. It's barely nine in the morning, far too early for the concoction she's sipping, but she nods after she draws back from the straw.

"This is delicious," She decides, "And you two are traitors, and I'm telling everyone about this."

"You should," Aaron laughs, stepping up behind you to press his shoulder to your own. It's comforting just having him there, and you relax against him as Penelope takes her leave.

"I mean it," She warns, wiping another stray tear from her cheek and sipping at her strawberry drink, "I'm telling everyone. I'm- I'm gonna hire some guy to fly a plane over the city, and the banner is gonna say, 'Y//N Y/L/N and Aaron Hotchner got married without me'."

"That's fair," You nod, not bothering to bite back a grin as she lingers in the doorway of Aaron's office.

"And so help me god," She narrows her eyes at you, once more falling just short of intimidating, "If you try to take some extended-sick-leave time, and I find out you're hiding a pregnancy from me? No amount of frappuccinos in the world will make up for it!"

"Noted," You call out as she leaves, and Aaron's hand comes up to press against the near-indiscernible bulge of your belly before the door even clicks shut.

"She's good." Aaron observes, and you reach for your own non-caffeinated drink with a grin that's hard to drink through.

"Let's tell her about the baby at lunch," You propose, "I think she's more than earned a secret to keep."
