Palermo is brilliant, but he is also a liability. He betrayed the team, got Nairobi killed, and only rejoined because he hates Gandía more than he loves chaos. In Season 5, he will likely get a redemption arc—and redemption arcs end in coffins.

The ultimate redemption for a character like Tokyo isn’t retirement on a beach—it’s a sacrificial, explosive blaze of glory. If she dies, she will take an entire army with her.
