It's hard to skate two clean competitions back to back, and I feel like it might have taken the wind out of their sails. But B/K definitely needed this win a bit more, they had a bad competition a week ago.
They were under huge pressure after Sasha and Mitya's magnificent skate and I think it got to them, the execution was sloppy in many ways that were not so at the 4th Russian Cup. And the We Are The Champions part is definitely weaker than the Bohemian Rhapsody part. But they kept their nerve and didn't fall apart, that was a job well done even if they might not be the champions here.
