Hello Joanna!!
Sablin was very, very close to Nicholas and Alexandra. You will see him endlessly in many photographs. Sadly, as far as i can remember, he was one of the first to abandon the Imperial family. I wish my memory could be better, but i think i read he was one of those who jump out of the imperial train as it entered the platform, in Tsarskoe, and run away. Saying afterwards that he had nothing to do with the Palace. When i think of this behavior of him i always remember a photograph taken in April 1914 in Livadia; he is helping the emperor to transport(?) Alexandra in her wheelchair.... He acted like a rat in a sinking ship.
