You did great on this chapter and personally I think his sister jess should be next. I think Brandy should be last because I'm a big fan of the girl who hates you stuff and on top of that, she can take him home which unlike being next door should be far enough away that he ends up having to get her attention in hopes that because they all got along in the past she'll help, of course it doesn't and she's quite unmoved by his plight and ends with her keeping him as a toy and laughs at his predicament while using and then discarding him after an incident which makes her think he's dead and laughs about it. Of course he's damaged but alive and makes it home on her unaware body. The ending is up to you, but if you go for a deathscene my suggestion is where his mother (or sister if your truly against using his mother for one reason or another) comes home and unawaringly finishes him off preferably not crushing until after death. Maybe fart or toilet, foot stink suffocation or sqeezing toe suffocation, or drowned in some way even if it's just in a bottle of her water.
