Yuzuru did talk to Denis after the second time Denis crossed his way. I don't know what happened after the third time (aka the punching board time). However a Japanese fan told me they have seen some news with Orser complaining about this before the short program event started.
Seriously???, I mean, I have been watching very close figure skating since 2007, 9 years, I know, this is not much compared with many people at this forum but still NINE years, and I only remember something similar. Yuna Kim accusing japanese skaters of interfering with her practices. I can´t help to note both are/were coached for Brian Orser. It is like Brian inflates his/her student ego at max, and they can accuse someone just like that.
ok, Yuzuru has nothing to lose, he has a lot of fans, contracts and a federation who, yes, is not the most supportive federation, but at least they are more powerful than the federation of Kazajistan. This can affect Denis invitations to shows at Japan, why japanese people would want to see a corrupt skater?, who just want to hurt to poor prince Yuzu?
it is not correct, he can yell all he want but why accuse openly to someone? Yuzu says that he think Denis did this intentional, ok, YOU think, YOU, that is not prove, he has thousands of fans and knows it perfectly, and of course the most of them will be agree with him. This is gross and inconsidered of Yuzuru.
Denis reputation is in doubt now. Look at this video hating Denis

When Yuna did this I thought it was very low, too far, but at least she did not accused to someone directly.
