Benno now understands how far ahead Main is, and paper/shampoo/hair ornaments are minuscule scrapes compared to the vast potential she still has.
But he also is very cautious not to break her and will probably search and find ways to solve or at least tame the devouring.
I wonder if he knows about how Main should has to remain motivated and avoid ill feelings, because somehow I think he tried to train her to some realities that align with that.
