Dollface, as Cara stated above JW is trying to mirror JM. Unfortunately for her she not articulate enough to pull it off. She tries to be firm in order to hammer a point home but ends up stumbling and crossing herself up. It's actually quite amusing and sad at the same time. She is also mistaking JM confidence for snarkiness, and in doing so is coming across as adolescent in her demeanor when trying to mimic him. On another somewhat related note, it is becoming apparent that the DT is becoming ever so concerned and wrapped up in JM, that they have lost their focus in their case.
