In the penultimate episode of "The Road Trip" titled "Pit Stop," the journey to Cherry's wedding takes an unexpected turn as the gang finds themselves stranded at a five-star resort, a detour orchestrated by Marcus on his dime. The episode begins with a brief debate about the pit stop, with Addie's agreement sealing the deal. However, things take a psychedelic turn when Rodney, in a moment of indulgence, consumes magic mushroom chocolate, setting the tone for a trippy and emotionally charged episode.
As Marcus grapples with the news that his father has cut off his expense accounts due to the car wreck, Deb attempts to explain to Addie her reasons for wanting her to move out. The focus quickly shifts to Rodney, whose mind is now wandering in a hallucinatory state. Despite Marcus's cards being canceled and Dylan losing his wallet, the group has no choice but to stop at Hotel Casa Reino Unido, thanks to Rodney's influence.
Addie heads for the bar, leaving the group at the front desk, and when the clerk finally arrives, she initially claims the hotel is fully booked due to karaoke night. After some negotiation, Marcus manages to secure a no-show family room for the gang. Before checking in, Dylan tries to engage Addie in conversation, but she dismisses him, preferring to enjoy herself when Britta Broad takes the stage.
In a flashback, Addie's life post-confrontation with Miles sees her sleeping in her van and using the teacher's lounge for freshening up. Her student, Justin, catches on and harasses her, even calling her a tramp. Dylan tries to reach out, but Addie ignores his calls, and their conversations are brief and strained. Meanwhile, after Lla fails to get pregnant again, Deb offers to carry the baby for her.
In the past, Addie gets drunk and rowdy, telling Deb she plans to sell the van and taking to the stage to sing. Dylan, wallowing in his own filth, is found by Marcus who convinces him to let Marcus try to mend things with Addie. When Marcus reaches out to Deb to find Addie, she tells him she's at Dylan's flat, a lie that Marcus goes along with. This leads to Marcus driving by the school and seeing Addie with Etienne, a sight that will later cause tension.
While Addie sings on stage, Dylan expresses his wish to understand what's going on in her head. Marcus attributes her behavior to classic abandonment symptoms, a conversation Deb overhears, leading her to join Addie on stage. The entire group ends up on stage, with Rodney's fall getting them kicked out. Despite Marcus's best efforts, he can't trick the clerk this time, but Addie's honest approach works, and they are allowed to their room with the condition they stay there.
In the room, Addie is ready to share something with the group but is unsure how to start. This moment is interrupted by a flashback to the night Marcus saw Addie with Etienne. He sees her leave with him to shower at his apartment, where he makes a strong advance, which Addie manages to avoid.
The next day, Addie meets Dylan for lunch, and Marcus has already filled Dylan in on seeing her with Etienne. Dylan assumes she cheated and is angry. Addie doesn't confirm or deny anything and storms off, telling him not to contact her. Later, Dylan questions why she couldn't tell him the truth, and Addie explains that she didn't want him to know she had nowhere to go. They both admit they haven't stopped thinking about each other since their split.
In the motel room, Rodney comes down from his high and tells Deb that if he doesn't wake up, he wants Cherry to know he tried to get to her. Deb distracts and puts him to sleep. Addie falls asleep in Dylan's arms, and they wake up next to each other. Addie tells Dylan their talk meant a lot, and she's ready to move on from him. Dylan tries to convince her that breaking up was a mistake, but Cherry's call interrupts them.
The episode ends with the group learning that Rodney is in love with Cherry and has stolen the van, leaving them stranded. This revelation adds another layer of complexity to their already tangled journey, as they must now deal with the fallout of Rodney's actions and the potential impact on Cherry's wedding. "Pit Stop" is a poignant exploration of the characters' emotional states and the consequences of their actions, highlighting the series' ability to blend humor, drama, and emotional depth.
