Episode 8 of "A Man on the Inside" begins with Didi engaging in a heated discussion with the staff and Charles, recounting the recent events. Clearly, Didi is dismayed that Charles and Julie deceived their way into the residence. But who is the culprit behind the theft? Regrettably, it transpires that Gladys is the thief. However, her actions were not malicious; her failing memory led her to believe that the necklace and watch were part of her own collection, stemming from her past as a costume designer. Charles employs his acting skills to persuade Gladys to surrender the necklace, pretending to be in search of costumes for a play. Subsequently, the staff discovers some of the missing items, such as the saltshakers, in Gladys' room. Once the mystery is solved, Didi dismisses Charles and Julie from the premises without hesitation.
As for Charles' fate, before departing, he confides in Calbert, breaking the old man's heart. Calbert, who had considered Charles a true friend, is deeply hurt. Charles clarifies that their friendship is genuine, but Calbert remains furious. The other residents, catching wind of Charles' spying, turn their backs on him in anger. They brand him a public enemy and spread rumors portraying him as an international spy.
Emily steps in to assist Charles in packing up and returning home. They share an emotional conversation about Victoria, and Emily helps her father sift through some of her mother's belongings in the garage, intending to donate them. This shared experience fosters a deeper bond between them, encouraging them to open up to each other. Charles confesses that on the day Victoria passed away, he had planned to betray their promise and place her in a nursing home. Thanks to his newly forged, intimate relationship with Emily, Charles finally manages to let go of his guilt. Furthermore, he embarks on a new journey, delivering guest lectures at the university.
Did Didi ultimately decide to leave? Upon hearing whispers of her departure, Julie and Charles promptly sought her out, engaging her in heartfelt conversation that swayed her to continue her stay. The entire community breathed a collective sigh of relief, rejoicing in Didi's continued presence. When Calbert confided in Didi, she revealed that it was Charles's persuasive words that had turned the tide in her decision-making. Reflecting deeply, Calbert reconsidered his abrupt severing of ties with Charles and extended an olive branch, mending their broken friendship. They reconstructed their bond, and Calbert joyfully shared with Charles that his son had opted to remain in San Francisco, forsaking a potential move to Singapore. Charles's counsel had brought Calbert closer to his son, fostering a deeper connection. Ultimately, Calbert extended an invitation to Charles to attend Elliot and Virginia's wedding, presenting Charles with a golden opportunity to mend fences with the residents and regain their favor.

She rang him up, and despite the lack of comprehensive details, he eagerly embraced the new assignment with enthusiasm.
