I’ve already made a post briefly summarizing the most important changes, but now let’s get a deeper look at everything I could find whose meaning is different now that we know about the party:
1) Victor watching the video of Yuri dancing to “Stay by Me & Never Leave”
Before: Victor saw the potential Yuri had and decided to coach him
Now: Victor saw the potential Yuri had and, considering the routine is about asking someone to stay by your side, likely also interpreted it as Yuri calling to him to be his coach.
2) Victor’s certainty in his choice
Before: Victor is so sure of himself he didn’t even worry that Yuri might not want to have him as a coach and simply moved to his place without asking.
After: he wasn’t worried because he thought Yuri remembered asking him for it and considering the video of him, Victor assumed that hadn’t changed.
3) The flirting and closeness
Before: Victor doesn’t understand personal space and/or is trolling because he knows how Yuri reacts to flirting
Now: Victor saw Yuri even pole dance half naked. They held each other and danced together. Yuri clung to him while dry-humping him. And Victor clearly had a thing for him at that moment. He didn’t think Yuri would mind the closeness so much because of how Yuri had behaved that night, and all the flirting wasn’t a joke but Victor sincerely interested in Yuri
4) Eros: the playboy was…Yuri
Before: Victor made a routine on Eros where a playboy has the heart of the prettiest girl in town then leaves her. This is likely modeled on himself and his playboy/idol character
After: Victor might have modeled the playboy after Yuri. Yuri showed up, stole his heart, then left to Japan without another word. Sure maybe Victor might not have been too much in love yet, but maybe still enough that it inspired him to make that song. A more indepth analysis of this is here.
