Maria Kallio steps into an undercover role during the investigation of an execution-style murder, her face tense under the dim lights of a seedy meeting spot as she meets suspects, her hand steady on her hidden weapon while she weighs her loyalty to the team against the risks unfolding around her. She navigates tense exchanges with the perpetrators, her eyes scanning every shadow in the room for threats, her breath controlled as she gathers evidence without blowing her cover. Back at the station, amid stacks of case files and flickering computer screens, Antti finds her alone in her office, his expression earnest as he kneels and proposes marriage once more, the ring glinting under the harsh fluorescent light. Maria pauses, her fingers tracing the edge of her desk, then nods and says yes, slipping the ring onto her finger with a small, resolute smile, her shoulders relaxing for the first time in hours. The camera lingers on her face as doubt flickers in her eyes, the weight of the day's dangers and her divided personal life pressing in, while the episode cuts abruptly to black without resolving the undercover operation's full fallout or her relationship with Koivu.
