We think of them as pairs skaters from Russia/Canada, but they must think of each other as persons. For whatever reasons they like each other.
So I don't find it odd, but I do find it a bit disappointing (only from my perspective) because Pelletier was a part of the B&S vs S&P drama. B&S put it behind them (clearly Katia also put it behind her) and they were decent in dealing with S&P while both pairs toured together. Verne Lunsquist went over the top saying the two pairs are friends now. I thought it was silly to repeat that Everytime.
I don't know if they were friends but I am sure the behavior was friendly. Actually even during the double gold ceremony B&S were a model of graciousness. Anton said in the interview "we are skaters. We are not politicals (his word)". They did their job during and after the Olympics - to skate and be gracious toward other skaters.
However, I know that in the USA (I don't know about Canada) B&S were not treated well. In Europe and Russia they received the respect they deserved.
I saw while attending their shows that in the USA the audience gave a loud cheer to S&P and only a polite applause to B&S. At one show the woman who sat next to me asked me - who are they (when B&S took the ice)? I told her they are the Olympic champions.
