Fun fact, everyone just got a reality check that Penelope is just a teen girl that they have been abusing because she isn't another girl, at least some of them did, and her almost dying made them realize that.
Plus, not everyone in the mansion are dicks enough to blame her for almost dying or to be jerks to a girl that recently had her neck slashed, apparently that is a bit too much even for them, at the moment, they are genuinely being nice to her, but don't worry, moments of abuse will come back according to the novel.
