Matthew Lillard reacts to the news:

Moments of quiet comfort by the fire in the Slytherin common room, after Romulus Crouch a boy in their year had publicly announced in their class that Procyon was an inadequate heir to the ancient and most noble house of Black, and an overall disgrace to the pure blood line and Slytherin title..

Sirius adores both his brother and his son so much that he does dye strips of blonde into his hair. He started this during his time at Hogwarts and it got Reg out of his shell, and he continues to do it throughout adulthood for Procyon

The idea that a Black having white hair is considered a curse by the family cause it’s seen as imperfection. Regulus also has this curse and fears for Procyon but Sirius couldn’t be happier of this outcome🫶🥺
