Great Hermione and Snape interactions, they're really well-written and enjoyable to read. The build up of their attraction felt natural and did not feel like an annoying detail to be rushed through to get to the next part of the plot/story.
Also a definite cheer on your insight about how Snape viewed the young Hermione/Lily connection. It is so logical that it feels canon and the next best thing is to make it fanon.
