One night when they lay in hiding outside a know Death Eater’s house, after a year of increasingly warm friendship, Tonks made an idle remark about one of her fellow Order members (‘He’s still handsome, isn’t he, even after Azkaban?’). Before he could stop himself, Remus had replied bitterly that he supposed she had fallen for his old friend (‘He always got the women.’). At this, Tonks became suddenly angry. ‘You’d know perfectly well who I’ve fallen for, if you weren’t too busy feeling sorry for yourself to notice.’
And the meaning of Tonks’s Patronus and her mouse-colored hair, and the reason she had come running to find Dumbledore when she had heard a rumor someone had been attacked by Greyback, all suddenly became clear to Harry; it had not been Sirius that Tonks had fallen in love with after all.
“But she wants you,” said Mr Weasley, with a small smile.
