See, this thread is why they teach literary analysis in school. Rape is often implied in fiction by reaching to touch the victim, while the perpetrator is left faceless. I had a hunch about what was up as soon she said that she wasn't allowed to make her brother mad and had to "act considerably" towards him.
Notice how he's reaching for her from above. Notice how she's wrapped in chains. Notice her horror at her brother showing up. Notice how she went great lengths to get away from him.
I have no clue how someone can see that a man broke into his sister's house and smashed something, and come to a conclusion that he's an oblivious airhead who's only crime was overshadowing her. Or see how she panicked at the sight of her brother and was so desparate to flee that she ran into oncoming traffic. There is literally no valid explanation but abuse.
The broken glass, with her slippers positioned to show that she's backing away, are solid proof that he at the very least psychically abused her.
PS: Narcassist isn't a shorthand for evil. Narcassists are abuse victims who developed an overinflated ego as a coping mechanism get through child abuse (neglect or otherwise.) Just say abuser or living piece of shit or whatever instead of showcasing your ignorance.
