The HBO crime drama "Task" concluded its intense narrative with the finale episode, "A Still Small Voice," written by Brad Ingelsby and directed by Jeremiah Zagar. This episode delivered a quieter yet profound epilogue, meticulously tying up loose ends and providing bittersweet resolutions to a story rooted in bloody vengeance and complex moral dilemmas. The death of Robbie Prendergrast in the previous episode set off a chain of subtle yet impactful ripple effects, particularly on FBI agent Tom Brandis, who had been relentlessly pursuing him.

Perry, whose actions had been escalating, faced the consequences of murdering Eryn. The truth about her death weighed heavily on him, and the Dark Hearts motorcycle gang, observing the fallout from the confrontation in the woods with Robbie and the FBI, deemed him a liability. They explicitly ordered Perry to eliminate his young protégé, Jayson, to avoid his own demise. However, when presented with the opportunity, Perry hesitated, momentarily sparing Jayson. The discovery of Eryn's body in the lake by police divers, still clutching a metal pants chain with "PD" inscribed, served as undeniable evidence linking Perry to the crime. Despite this, Perry clung to the hope of recovering missing drugs or the million dollars from their sale to regain favor with the gang. All signs pointed to Maeve as the recipient of the money, who, acting on advice, wisely hid the cash in a chicken coop, planning to claim Robbie hid it if discovered by police, or to use it to start a new life with the children after six months. Perry's on-again, off-again partner, Donna, concerned for Maeve's safety, contacted the Dark Hearts for intervention. Ultimately, her warning came too late to stop Jayson, who, upon learning the truth about Eryn's murder, fatally stabbed a frantic Perry emerging from a river, whispering "I know what you did" before leaving his body to drift downstream.

Meanwhile, FBI agent Tom Brandis, having confronted Grasso, intensified his efforts to expose his mole within the Dark Hearts. With assistance from Aleah, they re-examined Grasso's file, uncovering suspicious behavior. The sudden presence of young Sam Nance in Tom's care, a temporary fostering arrangement, hinted at Tom's evolving personal life. Simultaneously, Chief Dorsey, Grasso's superior, met with the Dark Hearts to discuss eliminating loose ends following Lizzie's death, positioning Grasso as an expendable asset. Despite Dorsey's public efforts to discredit Grasso, Grasso underwent a personal reevaluation, potentially spurred by Lizzie's death and a conversation with a former priest. He confessed to his sister, Frankie, admitting to financially supporting the family through illicit means. Tom and Aleah’s investigation led them to the wreckage of Cliff’s car, brutally run off the road by the Dark Hearts. Through Kathleen’s help, a satellite ping from a phone that texted Cliff on the night of a thwarted sting operation was traced to two blocks from Grasso’s house. As Tom and Aleah converged on Grasso's location, Dorsey was already there, poised for a clean-up. Grasso, using a blasting radio to disorient Dorsey, revealed his intent to turn himself in after two years of secretly working for the gang. However, before he could do so, Dorsey, revealing that the gang was heading to Maeve’s for the money, was shot dead by Grasso. Grasso, although wounded, prioritized warning Maeve, reaching her house ahead of the gang. In a climactic confrontation, Jayson held Maeve at gunpoint in the chicken coop, using her as a human shield. Amidst the chaos, Grasso, injured but determined, snuck into Jayson’s getaway vehicle and fatally shot him. Maeve survived, shaken but safe. Ultimately, Tom chose not to reveal the money’s location, honoring Robbie’s final wish for his family’s fresh start. Grasso, rescued before bleeding out, found a subtle form of absolution in Tom's words: "I never gave anyone penance. People beat themselves up enough on their own."

Maeve Prendergrast served as the audience's emotional anchor throughout "Task," especially after discovering her uncle Robbie's involvement with the FBI and the Dark Hearts. Actress Emilia Jones, who portrayed Maeve, elaborated on her character's journey, explaining Maeve's mixed emotions upon receiving Robbie's hidden money. While grateful for Robbie's successful plan to provide for his family, Maeve also understood the immense danger it placed her and the children in. Jones highlighted Maeve's inherent cleverness and resilience, noting her constant struggle to pick up the pieces and act as a strong adult figure in the family, despite her young age and the generational trauma she inherited. Robbie's sacrifice profoundly shifted Maeve's perception of him, fostering a deep respect for his unwavering commitment to his family's future. The interview also touched upon the brutal reality that Jayson was responsible for the deaths of both her father and her uncle, adding another layer to her personal tragedy. The intense final showdown at the Prendergrast house, with Jayson pursuing the hidden money, was a climactic experience for Jones, who performed her own stunts and found the physical challenges exhilarating. Maeve's ultimate hope, as imagined by Jones, is to build a comfortable and secure life for herself and the children, allowing her to prioritize her own well-being after years of shouldering immense responsibility.

The Brandis family dynamics unfolded in the background, showing signs of becoming a more unified front. Emily and Sara, initially at odds, grew closer, leaning on each other while their father was occupied. Sara questioned Tom’s decision to foster Sam, hinting at his past with Ethan. The daughters, despite their own struggles, teamed up to express concerns about Tom’s drinking and reckless behavior. The season culminated in Ethan’s sentencing for his role in their mother Susan's death. Tom, realizing his failure as a protector, chose to deliver the family statement, offering forgiveness to Ethan. He acknowledged his own faults, the impact of the pandemic on Ethan's medicine, and the importance of remembering Susan's efforts and their happy memories, not just the tragic mistake. Tom's declaration, "Ethan, I don't want you to live with this shame anymore... I forgive you. I love you," promised Ethan a home upon his release, signifying a profound personal healing for Tom. The series concluded with Tom's old friend from the priesthood suggesting that Sam should live with another family, while Maeve and Harper took a final look at the Prendergrast house, ready to embark on the new beginning Robbie had always envisioned for them, carrying his legacy forward.
