It's true that they looked like no pair before or since, but I don't think that their love for each other was key to that. They looked special even before they became lovers. I read Katia's book a couple of years ago and then I also remembered how she was always sitting alone in the audience at the 88' Olympics, watching each competition after they won gold together. He was so much older than her, I guess it was obvious back then that she had a crush on him (who wouldn't?) and that he cared for her and respected her. But they didn't spend much time together, apart from training.I saw one Soi number and it wasn't magic for me. I'm not implying who she loved more at all - likely ilia after so long but they looked at each other like no pair I've seen before or since.
The love was part of their brand of magic. I have never seen ilia do true pair skating. I enjoyed her with Bure too. I expect David to be an equal partner.
I think it's great that she was able to go on with her life like she did after he died and that she's still remembering Sergei together with her fellow skaters and the fans from time to time. And the fact that Ilia is supporting her is showing his respect for her and her life together with Sergei.
I expect Katia and David to look great together.
