Just the life of Poor Alberto. His father constantly abuses and belittles him, and even gets physical. During a ceremony, his father ignores him completely and claims that Bruce Wayne is the son he never had.
Selina has to watch Alberto get shredded by a ship propeller just after she started to bond with him, and part two reveals that he was her brother.
Part Two
Batman is injected with fear toxin and hallucinates his parents' murder. The great Batman is reduced to calling out desperately for his mother.
Sal Maroni's father is shot right in front of him, and the man is seen crying next to the body after he fails to catch the Holiday killer.
Harvey's mind is shattered after Maroni throws acid in his face, turning him into the supervillain Two-Face. Everyone also accuses him of being Holiday, when he is innocent. When he realizes that his wife is Holiday, he ends up taking the fall for her.
As horrible as Falcone is, he admits to Batman that he treated Alberto terribly and will never get a chance to make things better.
Selina tries to save Sofia, who she knows is her half-sister although Sofia doesn't, only for her to let go of her hand and fall to her death.
By the end of the film Selina has watched her brother, father, and sister all die in front of her.
A bittersweet one: As Carmine lays dying, Selina unmasks, and he mistakes her for her mother, calling out "Louisa". That was the one and only thing she'd ever learn from her father.
