Anne has spent the last night and the current day in her room, honestly kind of sulking.
Matthew calls Mrs Rachel a "meddlesome old gossip" when he hears what happened. Go off, Matthew.
Anne's being rather dramatic about her punishment like she's going to spend years in her room. It's been maybe 24 full hours. Just saying.
She agrees to apologize for Matthew's sake as he misses seeing her at meals very dearly, and they very much have a bond already.
Anne tells Marilla she'll apologize to Mrs Rachel and Marilla is relieved as she didn't know what to do if Anne didn't give in.
The narrative also dumps on Mrs Rachel again: "Good Mrs Lynde, not being overburdened with perception, did not see this."
Mrs Rachel sort of apologizes, but she's one of those people who says stuff like, "I'm such an outspoken person" and very ugh. She does suggest Anne's hair might darken to auburn, which pleases Anne.
She compromises by saying she hopes Anne won't need to make many more.
Marilla's heart warms and she tries to cover it, but barely manages.
And perhaps keeps them from murdering each other :P
