Thoughts I Have While Attempting to Fall Asleep

Thoughts I have as I am laying bed at night(after listening to Harry Potter): What point had Tonks and Lupin admitted their attraction to each other for Teddy to be born before the Battle of Hogwarts? What would the couple name for Lupin and Tonks been? Luponks? Topin? Nephadus? Reamora? (I personally like that one[But I would hate to tell my kid I named her Reamora because of Harry Potter]) And then I was thinking about other Potter couples; Longgood or Lovebottom? Weasger or Grangly? So on and so forth...
