[In this scene Okyausu sees his older brother dead ensnared in telephone wires and burnt to a crisp, he is distraught and holding on to any excuse to call his brother a good person]
Bro… I knew it was only a matter of time before this happened. I knew all the bad things he did in his life would catch up to him one day, but still… in the end, my brother- my brother used his dying moments to save my life, didn’t he?! Josuke, you saw it, right?![

[Unfortunately, I could not find the scene in English, but here it is in Japanese for refrence]

[In this scene he has the stand that killed his brother cornered, he is rather calm yet has a tone of bubbling rage burning inside him]

I didn’t. I knew who my bro was. The other shoe was gonna drop eventually. Someone was bound to snuff him out over something. That’s the thing about crime. No matter how far you try to run from it, it always has a way of catching up to you in the end. That’s painfully clear, even to a sap like me. So now for the business at hand. Tell me who your user is and where he lives. Do that, and I’ll spare your life, which is more than you deserve.

[With this line his facade breaks showing how truly angry Okuyasu is about the loss of his brother]
(growls) To be honest, I’m secretly hoping you won’t give me the info on your user! I’m itching to scrape you away, you glow-in-th-dark shit-head, so give me a reason!


[Again, I could only find the Japanese version for this scene but it should do fine for this scene]

[In this scene Okyuasu is speaking rather nonchalantly, and has a tone of longing for his brother as he speaks]
Oh, man, that dream was freaky as hell. I was walking around in this dark, open space when I suddenly saw this bright light. The source of that light was my brother… big bro Keicho. He asked me where I was planning to go next. I told him, “I’m going with you, big bro.” Even as snot-nosed brats, I could count on my bro. He made the best decisions, so I always knew I was in good hands. Then he said something I never expected. “You have to decide. Okuyasu, wherever you go, you are the master of your own journey.” I thought about that real hard, and, as soon as I said I was going back to Morioh, I woke up in the house. I had all sorts of sad feelings, though.
