You were one of the peculiar children that Miss Peregrine took care of but the more you grew up the more you had the idea of going to discover the world when you were of age, when you turned 18 you were already planning to leave and just at that time Abe (Jacob's grandfather) was also about to leave so you grabbed him to leave too, the two of you left the place, so the years passed (Jacob had already been born and was the age of the movie) until you received a letter from Miss Peregrine saying that please watch Jacob from afar since you were the only peculiar who was not in charge of a Ymbryne and who was not in a loop, and that by the way when Jacob arrived on the island you should visit her and the other children (you choose your peculiarity and your current age)
Miss Peregrine
