Was Simon's death ever talked about by Jack and his tribe?
Just like with Ralph and Piggy, Jack's tribe insists on not talking about it as a group. All the boys are thinking about it, but no one can find the courage to say anything...especially to Jack, whom most of the boys fear.
Not in a dirct manner. Many of the boys, like Stanley, want to bring it up, but cannot make themselves do it.
Jack insists that they killed the beast.
