S1E11 Furious All-out!/Plot

Rei Ryugazaki wants to know why Rin Matsuoka is swimming the realy, but Rin insists that he simply changed his mind. Rei remains unconvinced and continues with his second question, asking Rin about his personal feelings towards Haruka Nanase. Rin remains quiet and does not answer.

Rei goes on, saying that he knows that the four of them used to be close friends, as is evident in photographs, so he doesn't understand how it has ended in tension. Rin is angered by such personal questions and states that he doesn't have to explain anything. Rei says that he does because he, himself, is the victim of the tension. He joined the Iwatobi High School Swim Club after seeing Haruka swim, but doesn't know why they keep talking about Rin. Grabbing Rin by his collar, Rei tells him that it's his fault that Haruka stopped swimming. Rin is shocked by this heretofore unknown reaction and turns his back on Rei. Without hesitating, Rei replies that he wants to swim with them as a member of team, using Rin's past words against him.

The rest of the team visits Rei at his house since he missed practice, surprising Rei. After observing him, Haruka asks Rei if he went to find Rin. Rei confirms it and says that he also had his own reasons for wanting to meet Rin. The team then reassures Rei that he is part of the team and that everyone is irreplaceable.

At night, Makoto Tachibana and Haruka cannot fall asleep. Haruka confesses to Makoto that he appreciates him always being there for him and thanks him, before going out for a run. Makoto is shocked, at first, but becomes really happy. In the next room, Rei finds out that Nagisa Hazuki sleep talks, then notices that he has a text and leaves the room. While running, Haruka meets Nagisa, who tells him that he is out looking for Rei since he is not in their room.

At a playground, Nagisa admits to Haruka that he is nervous and scared of screwing up the following day. Haruka reminds Nagisa that it is thanks to him that they are racing Rin tomorrow since he came up with the idea of creating a swim club. Nagisa feels better and jokingly tells Haruka that he should show more gratitude towards him. When Haruka agrees and thanks him, Nagisa is taken aback before becoming overjoyed and jumping on him.

Elsewhere, Rei is meeting Rin. Rin says he wants to give a real answer to Rei and reveals that it is not Haruka’s fault that he quit swimming. In fact, it was because when he was in Australia, he could not swim well enough and felt that the Olympics were completely out of reach. After returning to Japan, he stayed away from his old Iwatobi team. However, after his impromptu race with Haruka, Rin wanted to swim again. Also, watching the Iwatobi team at prefecturals reminded him of his relay with them. Rin finally tells Rei that he is going to swim as part of the Samezuka Swimming Club relay team, wanting to show everyone how good he can be. Unfortunately, when Rin returns to his hotel, Samezuka Captain Seijuro Mikoshiba tells him that he being taken off of the relay team for not focusing on Samezuka's needs enough.
