So here is the idea. Challenge the person above you to write something non-canon that you would find to be a good challenge for them. Whether it's "Your character doesn't move and describe everything around them" or "Here is a scene have your character escape" or "I saw this on Saw write what your character would do" ect.
The point of this is to stretch your writing. All of us can get in a rhythm when we write, but if someone throw a wrench into the mix what will you do.
So challenge away and let's see what happens.
