This prompt is from a guest: What if Espo and Ryan caught Kate leaving the loft during 5x01, because they were on their way to tell Castle something.
I'm just going to apologize in advance for the copied dialogue from the show, I'm only using it to link together certain parts of the story. We all know I don't own, now am I affiliated with Castle in any way.
Kate slid out of Castle's bedroom, immediately noticing his eyes on her. She was about to reach for the door handle, but she felt as if there was something off. She juggled the shoes she was holding into one hand, and palmed her breast, feeling for anything under her shirt. Oh god, she thought, as she scampered back to Castle's room, sending him an apologetic glance in her wake. He was stalling his family, while she attempted to make a getaway.
She, once again, slid out of the room, and when his voice raised, she took that as her cue to leave. With her previously empty hand, now holding her bra, she grasped the handle and slid out of the door. Beckett expected to see a clear, cool hallway, judging on how late it was in the morning-everyone would be working-she was surprised to see Espo and Ryan step out of the elevator bickering about something. After she got over the original shock, she went into a panic attack. She would never hear the end of it if they knew how her and Castle had sex, especially when it's guaranteed their first round was done out of anger, hurt, and all of the pent up want from the years before. She tried to be casual and walk past them, but Ryan just had to trip over his own feet, and stumble into her. He looked up at her, "I'm sorry, I didn-" he stopped, noticing Beckett was the one who he knocked into. "Beckett?" He and Javi gave her a once over, before bursting into a fit of laughter, filling the near silent hallway with echos.
"Would you be quiet." she snapped.
"Before you say anything, before you even try to deny that you came from Castle's apartment. I'm just going to state the facts... Your hair is very mussed up. It looks like you threw your clothes on in the middle of a tornado, speaking of which, I think the zipper of your pants is supposed to be in the front." she glanced over her shoulder to look at her backside, and her zipper was, indeed, on the back. "You smell like sex. You have a vibrant look to you. You're flushed." Esposito took a deep breath, and was about to continue, when she stepped right in front of him.
"I wasn't with Castle okay? I saw his neighbor on the street, and damn is he hot, so I figured I could have a little fun with him." she winked and pushed between them, leaving them staring into space, mouths agape. The two soon recovered, and continued on their journey, briefly forgetting why they were there in the first place. After knocking on Castle's door a few times, they heard rustling from inside, and what sounded like moaning, but when Castle opened the door, looking and smelling very similar to Kate, they saw Alexis sitting in the kitchen, head in hands.
"She's, ah, hungover."
"Hmm." they replied.
"What's up?"
"We just wanted to tell you Beckett resigned from the force. We know you two had a falling out, but you deserve to know."
"Oh, yeah, I kno-." he stopped himself, "Really?"
"Yeaaah." Kevin drawled out, suspicions arising over his slip-up. "We are just going to go." he awkwardly pointed down the hall.
"Okay, bye!" Castle said a little too cheerfully.
Twenty minutes later, Castle knocked on Beckett's door, completely ready for an outburst from her. "So you here to apologize for hiding me in your closet?" she questions when the door opens. It was less than he was expecting, but he wasn't complaining.
"Let me explain, when I heard her voice, i reacted by instinct." he said, waving his arm about.
"Yeah, like the instinct of a sophomore in high school."
"Right." she turned around, her look plastered on his face. "No. Look, I-"
"Wait a minute," she interrupted, "You're embarrassed about being seen with me!"
"Now that, is not true. Look, I, this, I. Okay, this is all just very new to me, and call me selfish, but I wanna keep what we have, together, to ourselves a bit longer." she ponders over his words before speaking.
"Still it wasn't your finest hour." she said dismissively.
"No," he agrees, "but maybe I could make it up to you," his eyes meet hers with a suggestive look, "somehow."
She stepped forward, grinning, "Well I suppose we know your mom's not going to be barging in, we could go for a round, two."
"Well technically, it would be round four," there was a knock at the door. "She's stalking us, she knows."
"Who is it?" Kate calls out.
"Beckett, it's Ryan." her face turns desperate as she steps in front of Castle.
"Hide. Quick in that closet over there."
"Yeah, I'm not getting in there."
"Why." she question "I hid in your closet, why can't you hide in mine?"
"Why should I?"
"Because,"
"Beckett, everything okay?"
"Fine." she replied, turning back to Rick, "Okay, maybe I'm not ready for anyone to know about us yet, right no."
"You're here, just like I was there."
"Yes, the difference being I have my pants on. Or, are you embarrassed to be seen with me?"
"Okay, fine, just act normal... If that's even possible for you."
"It's me!" he says, a bit deflated. He positions himself trying to look nonchalant, and doing anything but. She gives him a quick nod before opening the door for Ryan to walk through. He stares at the floor, but when he looks up, he is quite taken aback by seeing Castle standing in front of him.
"Castle. What are you doing here?" realization flashes across his face. "I knew it. You weren't in his building to be with his neighbor, you were there for him, and only him. You two are together. You two are together. You two are together." he chants as is skips around the room. Castle and Beckett just look at each other, they wanted to stay secret for a while longer, but everyone knows that won't happen.
