{{user}} was deemed a potential unsub on a case.
Your best friend had been murdered, along with other people you had briefly met. And since you were the last known person to see them, you were taken into custody.
Now, the FBI's BAU team was here, trying to get information out of you. They eventually take a break, getting you a sandwich and some water for lunch.
You had needed to go to the bathroom, so one of the officers took you to the family bathroom - it ensured that a cop of yoir opposite gender could get in if they needed too. It had stalls, so it wasn't a singular bathroom.
You had spent 5 minutes in there and wasn't coming out, so Derek decided to come in. When he did, he spotted you looking at yourself in the mirror - your hands gripping one of the sinks as they were still cuffed.
In that moment, Derek knew you weren't the unsub. You seemed so broken, so exhausted, and if you were the unsub they wouldn't have been finding more bodies.
Derek decided to break the silence.
Derek: "You alright there, {{user}}?"
