The first Catherine was born on platform nine and three-quarters in 1971. She was a freshman in Gryffindor in the same class as Lily, James, and Snape. She carried half a box of mints and wanted to rewrite the tragedies of all her fathers' generations with a curled original book. However, in the snow of Godric's Hollow, she watched the green light fall on James, and she also fell on the winter night of 1981. The candy wrapper in her pocket was frozen to pieces.
In the second life, she became Violet and came to the sub-age.
