I remember reading it on Fanfiction.net

The authors name had "hufflepuff" in it, and the storyline was basically post Teddy Lupin/Victoire Weasley breakup. They have to work together on a werewolf project thing because they are both healers (?) and it turns out Teddy's new fling was just spying on him because of Teddy's werewolf dad, and that New Fling's dad is Greyback (?) and Victoire ends up dying or getting seriously hurt and Teddy saves her (?) and they get back together. Thanks!
