Challenge 1
Give first names to all characters that have not ( Enjolras & co, Javert, Thenardiers (?) , even Gavroche - that's only a nickname- and his two little brothers from the book)
Keep in mind that it was possible that some of them were not baptised - Javert as an orphan, Thenardier kids as neglected, so they could choose their own name according to their desires ( especially Javert)
Challenge 2
Choose the most appropriate sign ( zodiac) for your favourite characters
