Leta Lestrange and Theseus Scamander
- Zoë Kravitz as Leta Lestrange: Fans of the original Harry Potter films just about lost their sh*t when Newt casually name-drops the Lestrange family in the first Fantastic Beasts while referring to a woman from his past, Leta Lestrange. She and Newt were once friends and possibly romantically involved during their time at Hogwarts, but something obviously went wrong between them. In the sequel she's engaged to none other than Newt's brother, Theseus.
- Callum Turner as Theseus Scamander: Whoever was in charge of casting this movie deserves a raise, because Turner and Redmayne look like they're actually related. The War and Peace actor plays the Magizoologist's strict older brother, who is a celebrated war hero and works as the Head of the Auror Office at the Ministry of Magic. We have a feeling his engagement to Leta will spark some kind of conflict with Newt.
