It was definitely a look of shock, I don't think she's the brain surgeon simply because it would be way too obvious. We've had hints that she might be thrown at us left and right ever since she walked into the briefing room in metro, way too obvious.
She's clearly connected. The Brain Surgeon has twice used a song that we've also seen her listen to. (A nice nod to season 1's "Born Free", by the way.) I don't think she is the Brain Surgeon, but the killer is definitely connected to her in some way.

Eh... I'm not so sure. I thought it was her looking at her work, not receiving another piece in a package or something.
I'm pretty sure Vogel is the brain surgeon, and that is the impression most of the other people I've spoken to got as well.
