We're going to make this super-simple. Your challenge is to make something of this:
It's entirely up to you how that particular image comes up in your story. Maybe you've got a burning desire to write what happened before Scully came in the room? What if the conversation had gone down a little differently? Perhaps you've always wanted to try your hand at some Scully/CSM ... We'll just stop there, shall we?
So, the two rules for this challenge are:
a) reference the scene from the picture in some way
b) post a fic :)
You've got a full week until the next challenge, so have at it!
