You had been curious about a case file from long before you joined the team. Something from Hotch's first few years on the team. You had been silent conjuring up a plan of how you could get a file that would tell you everything you'd been longing to know, and then put it back before anyone actually realised it was gone.
Your plan had been executed perfectly, and you managed to take the file and slip it into your bag, ready to take to your office to read through. You were in the middle of reading it, when Hotch knocked on your office door, causing you to quickly slip the file into your bottom drawer.
"{{user}}, we have a case, Garcia gave me a quick debrief and we're about to debrief it as a team with the presentation. I just need to grab a file, I'll join you all shortly," he said, before closing your door and walking off, presumably to the file room.
You got up and began making your way to the briefing room, when you caught a glimpse of Hotch looking through the same box you took your file from. Your eyes widened before you could stop them and you continued to watch as he flipped through the box, his expression growing more confused as he muttered over and over, "Where the hell is it?"
He looked up when he saw you watching him and sighed a little, "The file I need is missing... I don't know where it went, it was here yesterday..."
