After reading hundreds of Castle fanfictions, I decided to write my own.

Disclaimer: I do not own Castle or any of the characters... Sadly.

Castle walked into bullpen with two coffee cups in hand like any other day. He walked to Beckett's desk and placed her cup on top of it. He scanned the room but she was no where to be found. Curious as he is, he looked for Esposito.

"Hey, no luck with those witness statements? You guys catch a break?" Castle asks

"Better yet we caught our suspect." Esposito says proudly.

"And I missed it! Where is he?" He asks, unwilling to miss anymore action in their case.

"In the box with Beckett." Esposito answers pointing across the room. With that Castle nodded and headed into the observation room.

Soon enough he is enjoying the cat and mouse like interrogation from behind the two way mirror, as Kate questions their suspect about the bombing still so fresh in their minds.

"Who put you up to this Bobby? Who gave you that backpack?"

"I don't know... I don't remember." He stutters, obviously hesitant and flustered.

"You don't remember.. How do you not remember?" She asks unbelievably, sounding almost amused.

"I was in shock, a bomb went off. Everyone was running an screaming-" Beckett cut him off.

"Okay so you remember what happened after the bomb went off, but not before." She questions, trying to get him to slip up.

"It must have been one of those traumatic Amnesia things-"

"Bobby! Don't lie to me." She huffs, getting frustrated

"I'm telling you it was all a big blank, it was the trauma-"

"It was not the trauma... You don't get to use that excuse." She said pointing a finger at him.

"I swear I don't remember."

"The hell you don't remember. Do you wanna know trauma?" She said raising her voice.

"I was shot in the chest and I remember every second of it!"

That seemed to be what won the argument because Bobby no longer had anything to say.

Castle's eyebrows furrowed. Quickly darting his eyes up to look at Beckett through the glass.

"And so do you." She said ending the argument, leaning against the wall behind Bobby. She crossed her arms, stared frustrated at the floor.

Castle's expression matched her's, scowling almost disgusted as he spoke to himself. "All this time..."

"...And you remembered?" Still shocked at her admission, he kept his eyes on her for a handful of seconds before storming out.

He walked at a fast pace back into the bullpen, heading straight for the elevator.

Beckett walked out of interrogation unaware of what she had just done. Her eyes landed on Castle's back as he was walking away.

"Hey Castle, where are you going?"

He reluctantly turned to face her.

"Anywhere but here." His voice was low and strangled. As soon as she made contact with his eyes she knew something was terribly wrong.

His beautiful ocean baby blues that were usually full of joy and adoration, were now stormy and dark with hurt and anger.

"Castle...wait, what's wrong." Kate barely finished before he resumed his b-line to the elevator.

"Castle.. Rick!?" She yelled at him from across the room. Before she could comprehend what was happening, the metal doors were sliding closed. Leaving an extremely confused Beckett to her thoughts.

*A few minutes later*

"Hey Esposito, how long ago did Castle get here?"

"Like ten minutes ago. Why?" Confused by her question Espo watched as Beckett's features turned to shock.

For the next few minutes she sat at her desk replaying everything she said to Bobby in her head. She needed to know what angered Rick so much.

Then it hit her like a slap to the face.

He knows. He knows I lied to him. Oh god Kate what have you done?

"Oh god Rick..."

She swears under her breath and put her face in her hands, then ran her fingers through her hair.

I have to make this right.

She ripped her jacket off her chair, ignoring Ryan and Espo's questions behind her and headed out of the precinct, to her car. Nothing mattered. Only him.
