I mean i was just thinking, the cautious and overprotective mother that Alix was, when she left her son in Toblosk with Tatiana and Olga in his state, i do believe she would have given them instruction on his care. Not to mention another thing i had been thinking about there had to been talk within the other royal courts about the disease, even their own court. Certainly that knowledge would have gotten to the older girls. I mean think of Olga, i mean if im correct they tried to set her up with Karol of Romania, im sure Missy was worried about the possibility of that disease, i wonder if it ever came up in a discussion between all of them...but like you said robert we're all just guessing here
