He did sexually harass her, but not to the extent of r**e. Like he inappropriately touches her and sits her in his lap where she can't really resist or negate his advances (ex, family dinner and in public), because he makes it look "harmless" doting for his sister.
He's fucking disgusting.
Wait so like, did that horrible scum piece of a brother, only beat ruby or did he do sexual things to her to? idk I'm kinda getting the vibe and if im right I swear that F**KING BASTERD OMFG
