Heartwarming / Grand Blue

• After hearing Aina's story of being humiliated for Tinkerbell's own amusement, Iori and Kouhei manage to trick the club's Captain Kudou into confessing to "Azusa", who's really Iori in drag, humiliating him in front of everyone attending the Male Beauty Contest in order to get back at him for his treatment of Aina.
• Despite Iori's aptitude and skill with tennis following Peek-A-Boo's money match with Tinkerbell, Azusa and Nanaka wonder why he didn't join the latter instead. Iori sarcastically replies he didn't have a choice (since Ryujiirou and Shinji coerced him into Peek-A-Boo), but having found something new to do (diving) has him given a new perspective and appreciation, a Call-Back to how he felt after the first time he dove into the ocean and exclaimed to Chisa how awesome it was.
• By all definition, Iori, Kouhei, Hajime, Shinichirou, Yuu and Kenta shouldn't even be friends: they will Troll one another, stop one of them from losing their virginity to their Childhood Friend and dish out all sorts of violence whenever they don't agree on something. What cements them as True Companions is when Sakurako deliberately sabotages Kouhei's chance at seeing Kaya's concert by stealing his ticket to the venue, while blasting at how pathetic Kouhei is for throwing away an opportunity at flirting with her and her clique. As the men are quietly seething at what she's done, Iori takes the initiative to pour a glass of beer on her; the guys leave on Iori's command, stating there's nothing wrong with Kouhei's Otaku hobbies - he's fine the way he is. Sure, Kouhei eventually did get into the concert (making Iori's actions moot), but it's the thought that counts, given how elated his expressions were about attending the concert altogether.
