A homeless person who just moments ago was shouting at no one, dies in your arms. Right before they take their last breath, they give you their glasses. Once you put them on, you see who they were shouting at.
okay but what if Tonks's parents had another child, and named it Remus, after Tonks's choice. Because her mother was kicked out of the Black family because of who she married, she would want to honour Tonks's choice too. So it would be called Remus Tonks.
