Only Murders in the Building: Why did The trio decides to question Dickie without revealing Loretta's identity.?

In the episode "Thirty" of the comedy-mystery series Only Murders in the Building, the trio of amateur detectives, Charles, Oliver, and Mabel, continue to make progress in their investigation into the murder of their neighbor, Tim Kono. Throughout the episode, they discover new clues, uncover potential motives, and establish a focus on proving Loretta's innocence.One of the pivotal decisions made by the trio in this episode is to question Dickie, without revealing Loretta's identity as his mother. They suspect Dickie may be involved in Ben's murder, and they believe that gathering information from Donna, Dickie's protective mother, could provide valuable insight.One of the key reasons for their decision to keep Loretta's identity a secret is to maintain the element of surprise. By disguising their true intentions and keeping Loretta's involvement hidden, the trio increases their chances of gaining genuine and unfiltered information from Donna. Revealing Loretta's identity could potentially trigger defensiveness or evasiveness from Donna, hindering their ability to obtain the information they need to solidify their suspicions about Dickie's involvement.Additionally, the trio suspects Donna may have a motive for wanting Ben dead. They explore the possibility that Ben stole CoBro, a company he worked for, from Donna. By questioning Donna without revealing Loretta's connection to the investigation, the trio hopes to uncover any resentments or anger she may harbor towards Ben.Throughout the episode, Donna acknowledges that she has covered up things for Ben but vehemently denies any involvement in his death. She discloses that Ben would often disappear on Thursdays, referring to his activities as meeting with "five whores." This information adds another layer of complexity to the investigation and raises more questions about Ben's personal life.As the trio continues their investigation, they gradually begin to suspect that Loretta may not be the true killer. Charles's alibi establishes his innocence, prompting the trio to shift their focus towards finding the real murderer to convince Loretta to retract her confession.The decision to withhold Loretta's identity also allows the trio to gather more specific information about Ben's activities leading up to his death. They track his movements, starting from Broadway and 35th and eventually discovering his involvement with a sewing circle. The members of the sewing circle reveal that they last saw Ben on the opening night of Death Rattle, where he helped sew personalized hankies for the cast and crew.By carefully piecing together the timeline leading up to Ben's murder, the trio uncovers various events and interactions that may have contributed to his death. Voice messages left by Ben express his distress and his feeling of being surrounded by untrustworthy people. They also learn that Ben had an argument with KT, the stage manager, and he was punched by Charles during a rehearsal. As they delve further, Donna mentions that Ben appeared bad, complaining about Charles and Loretta.Another crucial discovery is footage captured by Tobert, the behind-the-scenes filmmaker, which shows Ben engaging in a conversation with someone mysterious in his dressing room. This newfound evidence leads the trio to believe that this person may have poisoned Ben, causing his death.Despite their efforts, the trio realizes that they need more time to solve the case and free Loretta. They continue their investigation but become increasingly aware of the ticking clock. Mabel's birthday becomes a momentary distraction and a source of solace for the trio, but they remain determined to prove Dickie's innocence and uncover the real killer before it's too late.In a race against time, the trio hatches a plan to prove Dickie's innocence and secure Loretta's release from jail. They suspect Donna, who holds both motive and opportunity for wanting Ben dead. However, they understand that solving the case in time will be a challenging task.To confront Donna and potentially obtain critical evidence, the trio takes advantage of Mabel's bridal status and pretends to be her fathers to gain access to the courthouse. There, they find Loretta and convince her not to enter a guilty plea, sharing their belief in Dickie's innocence. Loretta reluctantly agrees to trust the trio, setting the stage for an intense confrontation as they prepare to uncover the truth.The decision to question Dickie without revealing Loretta's identity serves several purposes for the trio. It allows them to gather information from Donna while keeping her guard down, maintains the element of surprise, and preserves the potential for genuine revelations. Ultimately, this decision represents the trio's relentless pursuit of justice and their determination to unravel the truth behind Ben's murder, all while racing against the clock to prove Dickie's innocence and secure Loretta's freedom.
