Nathan decides to practice his own assertiveness in relationships by challenging Angela over their son's religious upbringing. Angela, a fervent Christian, refuses to allow Adam to be raised in Nathan's Jewish faith, so Nathan secretly brings his son to lessons with a tutor in Judaism under the pretense of swimming lessons. Seeking solace outside the house, Nathan opens his replica Alligator Lounge to the public under the name Nate's Lizard Lounge. The co-parents argue over a comedy skit featuring six-year-old Adam as 'Dr. Fart' and a joke about eating faeces, which Angela claims is a Satanic practice.
Nathan rehearses the confrontations with a fake Angela, and in one scenario, she harshly criticizes Nathan's emotional detachment and questions the ethics of the entire production. However, in their real final confrontation, Angela simply decides to quit the rehearsal. Nathan continues to raise Adam, now as a single parent.

Nathan stages a ninth birthday party for Adam, but faces a problem when Remy, one of the child actors who played Adam at age six, becomes attached to Nathan, calling him 'daddy' even after his scenes are over. Remy's mother explains that her son might have trouble understanding the difference between acting and reality. To discover what went wrong, Nathan repeats Remy's scenes with different actors including Liam (a nine-year-old Adam actor), an adult actor, and a mannequin. He then explores what might have happened if Angela had stayed with him and meets with the real Angela, who urges him to forgive himself, as her religious beliefs state.
In an attempt to truly understand the connection between parent and child, Nathan stages a new scenario in which he is Remy's mother Amber and Liam portrays Remy. They re-create the experience of appearing on The Rehearsal and becoming attached to 'pretend daddy' Nathan. After coming to the emotional realization that they should not have done the show, Nathan as Amber seemingly breaks character and tells the fake Remy, 'I'm your daddy.'

What If we could talk to animals? For as long as we've shared our lives with pets, we've been seeking better ways to communicate with them. In Washington state, Alexis Devine and her sheepadoodle Bunny think they've found a way of making communication a reality. Alexis went further than most, with a set of communication buttons, each programmed with a pre-recorded word to help humans and animals speak the same language. She has 90 buttons with which to express herself and even seems to combine them into simple sentences. Bunny is paving the way in pet communication.
The undisputed masters of verbal communication are our pet parrots. They have mastered the art of vocal expression. Some parrots have even learned to fool devices designed to recognize human voices.

It's the North London Derby - one of the most notorious games in the world. Arteta and his young squad prepare to take on local rival Tottenham Hotspur in front of a riotous home crowd at the Emirates Stadium. The pressure is mounting on Euro 2020 hero, Bukayo Saka to score his first goal of the season. For captain Pierre-Emerick Aubameyang, this game means far more than just team rivalries.
The narrative around Arsenal at the moment, they're only ever one game away from it being calamitous again. Mikel Arteta remains under pressure. So far in the league, Arsenal have played four games and only scored one goal.

Two months in, and on a run of convincing and emphatic wins, the team prepare for a tough set of away matches. Goalkeeper Aaron Ramsdale finds his footing, giving new strength to the team's defence. Defender Kieran Tierney suffers an injury blow whilst new signing Nuno Tavares shines in his debut, but a 10-game unbeaten run is at stake as the squad heads to Anfield.

Speculation is rife as fan favourite Aubameyang is stripped of his captaincy. After a bad run of results, the mood within the Arsenal camp is low and Mikel Arteta's decisions are under scrutiny. With Aubameyang no longer training with the first team, the focus shifts to the remaining players including Brazilian player Gabriel Martinelli.
As Christmas approaches and Covid causes chaos in the league, Mikel Arteta is forced into isolation as the team prepare to face the reigning Premier League Champions, Manchester City.
