at this point in the story how does yurio feel abt yuuri? does he still look up to him? does he hate him??
He has very mixed feelings about him now. On one hand, everyone knows that there must be a reason for Yuuri sleeping with Viktor despite hating him and the most commonly accepted one is that Yuuri is manipulating him, so that’s the view that Yuri is surrounded with. And if Yuuri is doing that, he’s cheating and has completely broken all of Yuri’s respect and kind of (not that he will ever admit it) hero worship of him. Yuri respected Yuuri for his skating and hard work and how he clawed his way up from the underdog to the top from sheer force of will and Yuuri manipulating Viktor to win undermines all of that respect. And even if Yuuri isn’t cheating to win, he’s still hurting Viktor in a way with what he’s doing, even if it’s Viktor’s choice to continue.
On the other hand, Yuri doesn’t want to believe that of Yuuri. He respects him and the accusations are there but Viktor denies them and there is no solid proof. So Yuuri might actually still be the skater Yuri thought he was and everyone else is wrong. But Yuuri must still have an ulterior motive for doing what he’s doing. Either he’s looking to gain something from Viktor by sleeping with him or it’s the other option that everyone else dismissed. He’s not hurting Viktor on purpose and it might actually be affection, or even love that keeps bringing him back.
So Yuri is completely stuck, either his idol is a manipulative cheat and just using Viktor like everyone thinks, or he actually care about, maybe even loves, Viktor but for some reason still jerking him around. Which brings Yuri onto his first confrontation with Yuuri.
“Hey asshole.” - You’re still a dick even if you are in love because you’ve been hurting Viktor
“Yes, I’m talking to you asshole.” - see above
“Don’t think I don’t know who you are or what you do.” - I know you’re sleeping with Viktor and I know you’re hurting him (but I don’t know if that’s intentional or not).
“The way I see it, this goes one of two ways. Either you actually do care about Viktor, even a little bit in that stupid fucked up head of yours, or you’re using him just like everyone thinks. So I’m giving you a choice. If you do feel something for him, you tell him and stop fucking him around. And if you don’t, you stay the hell away from him. Got it? - either you’re manipulating him like everyone in the Russian rink thinks or you care about him even though you’re still hurting him. If you do care then stop hurting him and tell him so that people know they were wrong about you. If you don’t then you’re a cheat and I’ve lost all respect for you and I will try and keep you away from Viktor like everyone else.
“I hope you love him.” - If you love him, I was right and everyone else was wrong. You’re not a cheat, you’re still the person I thought you were (and admired) and maybe you didn’t realize you were hurting him. If you love him, you can still be a good person and I didn’t grow up idolizing someone only to have that admiration broken.
So Yuri currently still has very mixed feelings about Yuuri and those wont change until it becomes clear to everyone that Yuuri was actually very much in love with Viktor and never, ever intended to hurt him
