In Episode 6 of "DTF ST. Lous," we find Carol and Floyd attempting to reignite their love life at Quality Gardens, watched by a skeptical Clark. Their session doesn't meet Floyd's expectations, as Carol abruptly ends it by saying that Floyd made her squirm. Hearing this from Carol crushes Floyd's spirit, and his daily life is irreparably affected. Her words echo in his mind, causing him to struggle at work and lose his usual zest for life.

Clark notices Floyd's distress and learns the source of his problems. To lift his spirits, Clark creates a new DTF account under the name "Tiger Tiger."
Meanwhile, Homer and Plumb continue their investigation. Homer pulls Plumb aside to inquire if anyone has applied for a position in her department. Plumb informs him that an application has been received, and she's waiting for a response regarding the background of the sealed conviction. They remain stumped about the identity of the recumbent bike rider on the day of Floyd's death.
Clark speaks with his attorney, insisting that he no longer wants to disclose any more information to the detectives. She tries to persuade him to change his mind because the interrogation aims to determine if Carol had a motive for murder. Initially, Clark remains silent but changes his stance when Plumb asks if Floyd knew about his affair with Carol.
Clark explains that he had a panic attack at work and decided to start cheating on his wife, which led to his affair with Carol the next day. He claims that the message he received from Floyd, which was the main piece of evidence, suggested that Floyd was unhappy about his affair. He didn't want to mention the throuple because he wanted to protect Richard from learning such things about his parents.
Plumb points out the "Tiger Tiger" account and shows how Carol's words had sapped all confidence from Floyd, making him feel insignificant and invisible. He no longer feels optimistic and can't shake off her words.
To further exacerbate the situation, he had posted his genuine self on the DTF app, yet no one was willing to engage with him, which further depleted his self-esteem and amplified his insecurities about his body. Clark explains that he created the account to lift his spirits. As it was a male profile, he assumed Floyd wouldn't pursue it further and ask for a meeting. However, things took a turn when Floyd became intrigued by Tiger Tiger and wondered if seeing him would arouse Tiger Tiger. Clark tried to persuade him otherwise, but Floyd was resolute. Despite not having a preference for men, the thought of Tiger Tiger becoming aroused in his presence was a confidence boost that Floyd desperately needed.
Clark couldn't confess directly that Tiger Tiger was a non-existent entity. He was concerned that Floyd was genuinely considering the meeting, given his obsession with the authenticity of erections and how arousing a man for him could alleviate his feelings of sexual invisibility. Clark was at a crossroads; he had to make Tiger Tiger real, so he devised an elaborate plan to pay someone to meet with Floyd as Tiger Tiger. He named it the Denny's Plan, which involved a restaurant in Chicago called Denny's.
During his business trip to Chicago, Clark planned to dine at the hotel for two days as it was located in an area with a high concentration of gay men. He sought someone who would agree to be paid to meet with Floyd and get aroused. He attempted to recruit the waiter but was approached by a random guy sitting at a nearby table who accepted the offer. The man followed Clark and arrived a day earlier. He began shadowing Clark, and when he saw Floyd, he canceled the meeting. Floyd witnessed the entire scenario when Clark went to speak with the man, leaving him no choice but to come clean.
At the end of the episode, Homer and Plumb now wonder why Floyd still went to the pool house if he knew that Tiger Tiger had canceled their meeting.
