Pairing: Emily Prentiss/Emma Frost
Summary: The members of the BAU are faced with hunting down a mutant killer. Other people may also be in pursuit. And Emily finds out that where there are mutants, divisive politics follow close behind.
Apologies: JJ gets some POV in this chapter! How strange! I'm trying to finish chapter 5 tonight, and hopefully then i'll know where this thing is going to end. (then i can start typing up the sequel. What is going on with me!)
