To be perfectly honest, I’ve noticed way less people trying to deny Victuri ever since episode 9, especially when compared to episode 7 (despite the fact that that was when they became canon).
Apart from the fact that whether the kiss happened or not was a point of debate (and it was a kiss, but to be fair, I can sort of understand if some people didn’t see it), I think it might all come down to the idea that true, tangible relationships don’t need visible, explicit kisses to justify them, that a single airport scene can convey all the relevant emotions, that what truly matters and what truly shows the connection of two people is what they say and how they act around each other (especially in times of trial) and not simply how and when their lips touch.
I think it shows that deep, serious relationships like that can be felt even without seeing the couple properly kiss, or say “I love you” or have sex or lay in bed together.
Don’t get me wrong, I still think that the kiss from ep 7 was hugely important, and what I’m saying here actually supports it - they didn’t need to show their lips touch to get the message across.
Same was the case with the airport scene in episode 9. They never said “I love you” or “I want to spend the rest of my life with you”, but those feelings got across anyway. We all understood it, we all felt it.
And the best thing is that this is true also for people who had doubts regarding Victor and Yuuri’s relationship. It wasn’t just the people who already believed they loved each other who felt it, it was anyone who was open-minded enough to allow a small possibility that hey, they might actually really love each other. And it all got across in the end. It convinced the people who weren’t entirely sure how to feel about their relationship and I think that is impressive to say the very least.
I just want to praise Yuri on Ice’s direction. I believe making people see things in certain ways and feel certain things is already a huge feat. Add to that the ability to do that without ever being explicit or direct about and I think it would be fair to call this a high form of art, also known as amazing story-telling.
