Summary: "Chamber of Secrets" from Ginny's point of view. In this chapter, we arrive at Hogwarts, watch the Sorting, and finally reach the end of the day.
A description of Hagrid on the Hogsmeade platform:
A small circle of first years huddled nervously around him, like scraggly ornamental shrubbery ringing a massive oak. That does not match the rest of Ginny's POV narration AT ALL, but damn, I love that line. :-)
I forgot to mention that chapter 1 introduces Apple and Daphne Rumluck -- though after that chapter, one probably thinks of them the other way around, since Daphne does most of the talking. Chapter 2 introduces Xanthe Delaflor, the third of my five important OCs. (The other two are Susan Ward and Sir Vladislav the enchanted armor. Why yes, this story is chock full of female characters! ...I should keep a Bechdel Test pass tally, come to think of it.)
We get the first mention of Ginny's thing for Muggle fairy tales, which is really MY thing for Muggle fairy tales doubling as a thematic through-line that ties into the whole distressed damsel "princess waiting for rescue" take on Ginny's character that CoS (unfortunately) lends itself to.
( cut for length )Bechdel Test = PASS, a dozen times over
(Chapter one also passes, incidentally.)
