Bo and Marc return to the apartment—only to find Kitty Hall and Norman holding everyone at gunpoint. Kitty offers a choice: work together, or not at all. When she turns her gun on Bo, Marc counters, aiming at Norman. “Maybe we should talk,” Norman mutters. A shot rings out—Kitty drops, hit in the leg. Behind her stands Ellie Smith. She knocks Norman out cold and nods at Sasha. “She called—I came.” Ellie explains she’s been leading a resistance against Mercenary from inside Bank City. With Kitty bleeding, they demand answers. The mansion was a trap—so where’s the real base? Cornered, Kitty confesses: the local power plant. It’s a front. Marc, Bo, and Finn head out to investigate. Back at the apartment, Kitty warns them—Mercenary knows their location. A countdown begins on her watch. Brutas rips it off—three seconds left. A plane appears outside. Meanwhile, at the power plant, Marc’s team is swarmed by twisted human experiments. Fighting through, they climb to the top of the main smokestack. Agent Gunn appears, cornering them. Finn reveals a monster bit into his neck—infected, dying. Desperate, Marc lunges at Gunn. His touch turns Gunn’s wrist to gold. “Mercenary experimented on me,” Marc tells Bo. He kicks Gunn into the chemical vat. Finn collapses. There’s no saving him. They leave him behind. When they return, the apartment is burning.
