Their favorabiliy goes up because Peneloppe act like more mature and not like the brat they know before.
They didn't really hate her because thir not insensitive when they ear that she is mistreted by the servant or themself. Their just chock because their didn't really think about Peneloppe point of view at all.
Like pink brother who said after the meal case "you should make a tantrum like always" and when Peneloppe said that it's what HE want her to do, he was chock because he know what will happened if she really did that (no one will listen anyway) and understood that there is a problem.
Same with the father/elder brother, they didn't expect her to be sorry and thought that it's good first but everytime theyr call her, she excuse herself so they's chock and ask themself why she act like that before realising they always call her to scold or punish her and that make them feel like shit.
Once they put themself in Peneloppe shoes two second, they sympatise and their favorability rise.

Well they just don't realise how they act all this time. It's quite frequent in a relationship that the abuser doesn't realise it.
