Both Blake and Annie would produce some interesting shadow selves. (Blake:Why isn't it disappearing?! Why is it talking?!)

But if you need either in the role of rescuer, that's in Blake's nature even if she is in a dark place at the moment. Annie does on occasion do a good deed on a whim.

Both would be able to handle the shadows and fend for themselves in there for a good bit too. I'm game for whatever works.
