Ficlet prompt from howthisworks-caskett: I'd love to see the scene from Probable Cause where Beckett shows Castle the emails Tyson faked between him and the victim. Beckett later tells Lanie he looked like a scared little boy then, but I'd love to see that scene play out.
"Kate," Castle breaks the silence that had fallen over the room as he'd read the pages in his hands. "I swear to you," he looks up at her, "I haven't been with anyone since long before you and I were together, and I definitely haven't been unfaithful to you," he stands up and steps towards the bars. He glances in the direction of the guard's desk and lowers his voice. "I love you, Kate." "I know you do, Castle," she sighs. "I didn't write these emails either, I promise," he continues before she can say anything else. "I...I can't explain any of the evidence you've found against me, and trust me when I say I wish I could, but I didn't even know this woman, let alone kill her. Please," his eye widen desperately and brim with tears, "Kate, please. I'm innocent on all counts." Beckett reaches up and pinches the bridge of her nose. She doesn't like seeing him scared and pleading like this. She's supposed to be able to trust the evidence, but she's also supposed to be able to trust Castle, and she doesn't know what to do. Her head and heart are at war with each other in a way they've never been before. She has no words in mind, nothing to say that will make this all go away. All she can do is keep working, see the case through, and hope that she can find what she needs to put their lives back in order. "I've got to go," Beckett looks at him and clears her throat. "I need those emails back. I can't let you keep evidence. I shouldn't even be letting you see it." "Kate," he gives her the pages, letting his fingers trail over hers briefly before pulling his hand back through the bars. "I know you can find something out there to exonerate me. I need your help, but even more I need your trust," his voice breaks. "At least trust me about the emails and the affair being fake. You're the only -" "I'll keep looking, Castle," Beckett interrupts him and bites the inside of her cheek to keep from crying. "That's why I have to go. I'll be back tomorrow, unless I find something before then. I'll tell the guard to make sure you stay as comfortable as possible." She turns and walks away from his cell without giving him a chance to finish what he'd been about to say before she cut him off. She needs to stay strong, at least in front of him, and there's only so long that she can fight off the physical manifestations of her emotions while hearing him remind her of his love and beg for her trust and help. If he thinks she's giving up on him, he'll give up hope too. She looks down at the folder in her hand. It feels heavier than it is. The paper and ink it holds are more than enough to prove motive for Castle to be the killer. Between that and everything else, the case appears to be airtight. That doesn't matter though. Appearances can be deceiving and somewhere there's a crack that will let the truth slip in and she's going to do whatever it takes to find it.
