I've read that in K. Pleshakov's The Romanovs, a family saga" and Victoria fancied Alexander when he was younger (evidently they wouldn't have been allowed to marry for state reasons, not to mention religious reasons), and when she saw him later, for her son Alfred's wedding, she was shocked to find him so thin. She felt very sorry when he was murdered in 1881, saying "poor, poor emperor" and that he didn't diserve such an ending.
