There was a warning, at the very top of the chapter.
Tbh I also hated this rape scene (it showed just too much details) but it’s better than having a rape scene being played down like it’s nothing....
from plot it still was pointless rape, it was a bullshit reason for the plot. and they didn't need to be so graphic about it like we enjoy watching all those details.
and you right, there wasn't any warning before Leo come and kill them. which was the worse!
There wasn't a warning for the graphic rape but there was a violence warning on the chapter where Leo kills the rapists.
Everything is ott in this but did the rape have to be too? I guess using the entire camp of men vs just one was so he would know what Leo went through, which is bullshit, but there was no reason whatsoever for the fisting. And there wasn't even a warning! I just hate when rape is used for character development in entertainment. Stop doing this.
