A/N From a fanfic prompt on tumblr. Thanks to I-Blindside. I did changed a few things, because the plot bunnies made me. All mistakes are mine.
Lanie was always in the habit of clearing her phone of unwanted photos. Mostly because Javi could get too inquisitive. After today, she'll never forget to keep up with that task again.
"Babe," Kate Beckett whispers into her partner's ear. "Can you run down to the morgue for me and find out if Lanie has that crime scene photo for me? She must be busy, she's not answering her phone"
"Of course Kate." Rick says as he speaks quietly into her ear. "We both need to get home and get some rest. I'm ready for this case to be over."
"Castle, take my phone, and click on the photo folder from yesterday." Lanie says as she hands the phone to Castle
"And be quick about it, we need to get that photo to Kate"
Rick understands. It's been a long week, and he just wants to get Beckett home so they can both get some much needed rest. He still has so much guilt about what happened on their wedding day, but they finally seem to be heading for some sort of solid ground. So he grabs Lanie's IPhone, and starts to look for yesterdays crime scene photo, when his finger slips and lands on the file for May 2014.
Lanie realizes instantly what must have happened, when she sees Castle's face fall as if he'd just been shot.
"Oh God, oh God! Castle! Rick! I'm so sorry. I thought I'd moved that to my PC."
Castle tries to shake off the upset something as small as a photo, turning his world upside down again, to no avail. Lanie sees as the first tears escape from his eyes. He rushes to swipe the tears from his eyes, when Lanie hops up from her computer station and grabs him by the shoulders.
"Richard Castle, you listen to me. This was not your fault. Kate told me about the memory chip from the bank in Montreal. She knows that what happened was not your fault."
"What? You didn't think she would tell me? Of course she told me Castle. She knew she was right all along." Lanie says irately when Castle tips his head, puzzled.
"Kate believes in you Castle, and most importantly, she loves you with all of her heart."
Rick nods his head in agreement and says, "OK Lanie." As he turns back to the phone to call up the correct photo.
"She looked so happy Lanie. Was she? On that day." Rick tries to force a tight smile as he hands the phone back to her.
"Oh Rick, I didn't think it would ever be possible to see Katherine Beckett so happy."
Lanie looks up from the screen in time to see the tears threatening at Castle's face again and stands back up. "Look Rick, what happened, happened. You two will have your chance. Let's get this done so we can all go home."
They get the photo sent to Kate. After a long day at work, made even longer with so much guilt swirling around him again, Richard Castle takes his bride-to-be home. He doesn't sleep for four nights after that.
