I found the whole arc with the protag’s estranged mentor being the one who leaked the financial data genuinely surprising, but looking back the hints were there—those weirdly specific phone calls in earlier chapters, the mentor’s insistence on 'cleaning house' in a way that felt off. The twist isn’t just that he was the leak, but that his motive was protecting his own daughter who got caught up in the mess, which reframes every previous interaction between them. It’s less about pure betrayal and more about a desperate parent’s choice, which makes the moral conflict way stickier.
Then there’s the secondary reveal about the 'burner' account the main character thought was a dead end—turns out it was actively messaging another insider during the time jump, implying the corruption goes way higher than the initial corporate rivals. The chapter ends with the protagonist realizing the entire investigation has been subtly manipulated from the start, which shifts the tone from a straightforward revenge plot to a paranoid thriller where she can’t trust her own allies. The pacing really sold it; the mentor reveal happens mid-chapter, leaving you reeling while the rest of the pages build this creeping dread about who else might be compromised.
