What if the mole... (Spoilers, sort of)
Doesn't know that he/she is a mole. Roman and Shepherd were talking about "activating" the mole, so maybe there isn't a traitor walking around, but they have something REALLY sensitive about one of them or a strong motive for forcing them doing something, but are waiting for the right time. I know this has been overused in the show, but it is a possibility. I have the feeling it has something to do with Allison or Kurt.
Is this real? Or has this been happening inside my head?
