Alixz,
I'm interested in what you say about N being in contact with Mathilde in big + small ways over his lifetime. I agree, but wonder if there is any evidence. Undoubtedly, he could make eye contact with her when he sat in the first row at the Krasnoe theater (which is mentioned in an autobiog. by a Mariinsky dancer, Anatole Bourmann).
Dancers used to come to the royal box, too, for recognition -- but did adult dancers come, or just the Imperial Ballet school kids? MK mentions that N+A gave her a serpent brooch on her 10th anniversary recital, but it was delivered by Sergei Michailovich. I can't figure out if the last time they ever spoke to each other was in 1894, or if he continued to walk backstage, as Tsars had been doing for decades. Do you know?
I think that it is Coryne Hall who says that Alix forbade N to attend any more Imp. Ballet School recitals, like the one he attended in 1890. But I seriously doubt that, in fact, I think she was unaware of evidence to the contrary. Bourmann describes how the Tsar came into class one day unannounced, and then had lunch with them. It is a moving description. Nijinsky had gotten into a fight earlier, and had a 'shiner.' Bourmann said something like 'let it be recorded that there was understanding in his (the Tsar's) eyes as he scanned the black and blue cheek.' (a reference to hemophilia...) Then N told the 2 combatants that 'they had had their fun' and had to pay the price by not getting any dessert!
