Now, here is the expanded, chronological, narrative description of the ending:

The episode reaches its climax inside the Preggo crime family's hideout, a converted maternity ward where Donna Cordderero and her gang of pregnant mobsters are gathered. Detective Marvin Flute, undercover as the suave Italian mobster Roberto Stanlitucci, is deep in the operation, trying to win the Undies Award for best undercover work. The atmosphere is tense, with the women preparing for a major drug deal. Suddenly, Donna's water breaks, and chaos erupts. Flute, still in character, tries to maintain control, but as the situation spirals, he is forced to help deliver Donna's baby. One by one, the other pregnant mobsters begin going into labor, and Flute, now fully in the role of Roberto, delivers each baby with surprising competence and calm.

During the deliveries, Flute is struck on the head by a falling piece of medical equipment. He stumbles, dazed, but continues to assist, his speech and mannerisms becoming increasingly Italian and detached from his real identity. By the time the last baby is born, Flute is no longer referring to himself as Marvin Flute--he is fully convinced he is Roberto Stanlitucci. The Preggo crime family, impressed by his skills and loyalty, embraces him as one of their own. Donna, holding her newborn, thanks Roberto for saving her life and the lives of her crew.

Back at the Grimsburg police station, Flute is brought in for debriefing. His partner, Summers, watches as Flute, still in character, speaks with an Italian accent, gestures dramatically, and refers to himself as Roberto. Summers is stunned but notices that Flute, as Roberto, is more open, friendly, and emotionally available than he has ever been as Marvin. Summers is faced with a choice: report Flute's identity crisis and risk losing the new version of his partner, or let the situation continue. After a moment of hesitation, Summers decides not to report it. He tells Flute, now Roberto, that he's glad to have him as a friend.

The episode ends with Flute, still believing he is Roberto, walking out of the station with Summers. Summers smiles, accepting this new dynamic. Flute's fate is left ambiguous--he is no longer the detective he once was, but he has found a new identity and a new friendship. Donna Cordderero and her gang are arrested, but the focus remains on Flute's transformation and Summers's decision to embrace the change. The final scene shows Flute and Summers sharing a moment of camaraderie, with Flute's Italian persona fully intact.
