You are focusing too much on Anissina and Ilya, but my comment was not about them. I took them as an example to say that the fact that Nikita left Elena doesn't mean it's not gonne work for her or Ruslan, whether they are going to end up together or not.
On the contrary it might work very well, or even better, because it is also about motivation, and Anissina found herslef in the same situation and look her career. It's about how someone can react in similar situation.
As Ilya himself said about Elena and Ruslan: "Both are emotional, colourful, young, besides, they are the hurt party, which will give them a boost." He knows what's he is talking about. It doesn't mean that he has regrets for his choice of course.
I agree with you about Ilya. He really was a great dancer and would've loved to see him skate with Navka.
I can't picture him with Angelica tbh.
