Honestly this episode changed everything (spoilers below)
Before today’s episode the scene where Victor wanted to have a photo with Yuri was more like a yes from an idol- something you wouldn’t expect because he is far away from where you are.
At least that’s what Yuri thought it was all about because he didn’t remember the banquet. And that Victor checked on him even before the Japanese got drunk
Maybe Victor did this because he got a crush on Yuri, maybe because he felt sorry for his loss in GPF, but honestly it doesn’t matter because by the end of the evening he knew that he just loved the guy. And he could have suspected that Yuri in some way loves him too.
So when he sees Yuri skating his routine, Victor knows exactly what he has to do. Fly to Japan. And become Yuri’s coach or more, if he asks.
It got so much deeper now we know both sides of the story, because both of them, Yuri and Victor were attracted to each other since the beginning and got close as the time went by
