It honestly didn't really come as much of a surprise to Katherine. It wasn't like it was the first time that she and one or both of the Winchester boys ended up down at the station, and not when they were posing as feds. "If you insist." If there was one thing that Katherine had learned, it was that going along quietly seemed to be for the best. Of course, sometimes the accusations were absolutely insane and she couldn't bear to bite her tongue any longer, but usually she tried to just do and say the right thing. Of course, Dean usually had a tendency of saying the wrong thing or attempting to flirt at the wrong time, and that never really went over too well. Thankfully, before he could actually say anything that would have been facepalm worthy in Katherine's eyes, one of the feds, the blonde women's, phone started ringing. "Garcia, slow down. Alright...now breath....okay, now repeat what you just said and more slowly this time..."
[Garcia totally ran their faces through facial recognition and their actual names totally came up and she's totally freaking out over the phone to JJ right now in case you didn't know what the call was about
