I think the woman in Danielle's pictures is Raven, the girl from the restaurant in episode 11. Raven is different from the boss lady -- we see both of them in episode 13 making different resolutions for the New Year.
I was wondering that as well. The girl defiantly LOOKED like Raven pre-purple stripes. There are a couple things that I'm still very curious about:
1. What is Danielle's current mental state? Was she actually triggered by Derek? If so, why is she doing serial recruiting for Adrian? If she's totally clear-minded...then is she trying to make Adrian in control to over-throw Derek, using her now known hypnosis skills?
2. Was Danielle actually hypnotized in the therapists office, or was she faking it? What she told the therapist seems to run contrary with what we're finding out about her past.
This story has some nice twists and turns in it
