(Meredith Viera’s voice-over)
In fact, she says dead Professor Lupin's son Teddy is one of the main reasons she wanted to write the epilogue.
J.K. Rowling: To hear that Teddy Lupin -- Lupin's son is obviously okay. That he has an ongoing relationship with Harry and that he's-- he must be quite happy and he's got a very good-looking girlfriend because I think he's kissing in the epilogue his-- Bill and Fleur's eldest daughter.
Meredith Vieira: And why is that important?
J.K. Rowling: Because he's been orphaned. And I want-- I want to show that he's okay. And I want to show that because the world is a better place, he's having a happier-- and then I started to cry. So obviously Teddy Lupin's very important to me. I just-- yeah. I-- having killed both his parents, I really wanted him to be okay.
