Will they be Human err Wizards/Witches or Werewolves??
I read in a J K Rowling interview how she found one fan's remark saying Tonks and Lupin can have many multi coloured werewolf cubs together very amusing and she hooked them up together after reading that...
My take on this is... If they ever have children they will be werewolves who are able to metamorph to a Human form every full moon night... 😉😉
