Comments of chapter undefined of Transmigrated as a Secret Agent Into a Novel

Hold up there is a plothole here. How could the mc read about Alex Hart being found dead in his room? Alex Hart being found dead is the 'unaltered' timeline where the mc does not possess him but we already know the novel does not depict the original timeline but the altered one where mc usurps Alex Harts body cause it depicts his appearace as Silas.
