There are so many things to appreciate about every single line and every single shot in this episode, oh god.
This is the first time that we’ve seen all the difficulties Rin faced in Australia. The fact that he is talking about them shows how much he has grown; how much stronger he has become, enough to want ‘revenge’; enough to desire to come back and set the record straight. Enough to share his feelings in depth.
But that it is Haru he is telling this to though; that is so so important. Until now Rin had been so vague; only saying the necessary and never giving any details. But this time he is sharing it all; he is baring himself open and he does it on his own. Beause he wants to share it with Haru. Because he understands how Haru must be feeling. And because he wants Haru to know the full extent of the importance of his influence on him. He wants Haru to understand him just as much as he wants to understand him.
And what Haru says in turn:
This line, the way it was delivered spoke to me. Just like Haru became Rin’s bechmark - I feel that Haru has always been looking ahead at Rin, too. When Rin said “To be honest, it had never occurred to me that I could lose to someone.” Samewise, it most likelt never ocurred to Haru that there could be someone who ‘understood’ water better than him. So he picks up running, he starts adding in actual effort - because Rin himself becomes to Haru what Haru is to him. It goes both ways. They’re always aiming to never fall behind each other.
And this to me was another showcase of that. Of what zakki said, that to someone like Haru Rin 'shines'. Look at the way Haru words it; as if he felt that Rin had more experience than him, was ahead of him.
And then come two things that were so important to me.
One is that just like Rin wanted to share the hardships he went through in Australia with Haru; he also wanted to share the upsides.
That all those “kinds of things Rin saw”, all those “kinds of experiences Rin had" over Haru; they are things Rin wants to share with Haru. He did not wish to flaunt them, or leave him out of them; but to share them with him.
And the second is this:
Rin is effectively showing Haru the path he should take (again: a two-ways street). By bringing him here into his world - Rin gave Haru the key to his future, the key to discover his dream.
Because just like in S1; when Rin lost himself in his self-doubt and his fears and his problems but Haru never lost sight of Rin - no matter how lost Haru was up to this point,Rin has never lost sight of everything he knows Haru is and can be.
