The second episode of Oshi no Ko titled "Third Option" delves deeper into the complex relationships between the characters and their ambitions in the entertainment industry.

In this episode, the series explores the various pitfalls and dangers Ruby faces as she pursues her dream of becoming an idol. Despite her enthusiasm, she seems unaware of the harsh realities and risks that come with fame. The episode shows how recklessly she seizes every opportunity without considering the potential consequences, and how hard Aqua tries to protect her from harm.

However, Aqua's overprotectiveness is a double-edged sword. While he genuinely cares about Ruby's well-being, his actions often have unintended consequences and put her in even riskier situations. This dynamic adds further tension to their relationship and raises the question of whether Aqua is truly intervening for Ruby's sake or if he is driven by his own need for control and revenge.

The episode also introduces an interesting conflict with Kana, who recognizes Aqua as her former co-star. While Kana's excitement about their reunion hints at a potentially positive relationship, Aqua's reaction suggests deeper issues and unresolved tensions between the two characters. This development adds another layer of complexity to the story and promises to further challenge Aqua's priorities and loyalties.
