So, not only do I have to write her correctly but I have to introduce these two characters through the prism of her perceptions which are impacted greatly by her ability (which is newly come to her and one she doesn't have anyway of controlling at this point).
So, I left it at that paragraph and then came back the next day...and suddenly the words were flowing, just pouring out. I managed to get down on paper everything I needed, while honing her POV voice. (She's always been the most difficult POV character for me, but I think I'm finally getting the hang of her. How to present her ability and the dramatic impact and influence it has over her was what was missing before.)
I also think I've come up with a structure for the book that will allow me to make POV switches as needed and not worry about the individual chapter length. I really do need to plot a loose outline for the reworking of the whole opening section of this WIP.
It's an interesting process: re-writing and reshaping a section of a story already written.
