Actually, that's a fantastic question. Tatiana has always been my favourite, but less for her beauty than the fact that I saw her as the most like me (Olga is a VERY close second), and I have a great deal of admiration for her character. The one to take over when Alix needed rest and Aleksei was sick was Tatiana. Tatiana was a more capable nurse than her more sensitive sister, and Tatiana was trusted enough to be put in charge of Aleksei and the household at Tobolsk when Nikolai and Alix left with Maria. Tatiana was also a dreamer and greatly inclined to help others, like Olga, but did so quietly and in a practical manner. She was regal, but also had something of her mother's shyness. To me, she's always been very human, just like her sisters, and I can certainly relate to that capable, practical nature. That's me, the cool-headed one running the show in a crisis. lol
