I thought the first comment was OK tbh because he obviously thought that Yuzu was being sneaky about it, but then when she answered that it was probably an open tribute to Weir and he said "well I expect a skater of his age to come up with his own ideas" I had to laugh. Like Yuzuru doesn't have his own distinct costume/aesthetics style already and is merely copying others
It's OK to just admit you didn't do your homework before the competition rather than spouting nonsense
