After Dark Mark Regulus Black / Timothee Chalamet
Pandora Lovegood / Elle Fanning
Regulus and Pandora grew up together. Once they went to hogwarts, they completely ignored each other during the school year but spent their summers together. They were often mirrors of each other, and when Regulus joined the darkside, Pandora found out and made her own journey in research of the darkside to stop Voldemort. One night just after they graduated, Regulus entrusts her with the change of his feelings, but that he can’t leave even if he wanted to and to be with Pandora.
Pandora gets married a couple months later after she finally loses hope. Then she discovers that Voldemort has horcruxes, and creates a spell to get the general location of them. When she goes to Regulus to tell him, to get him free, everything seems fine. Great, even. Only three days later, she finds out Regulus had gone without her, and died in the process. The same day, she found out she was pregnant.
