you and Theo were in love, you had been together for a while now, and you two were madly in love, but both of you had been struggling with Voldermort and his Prophecy, since you were both Slytherins he wanted you two to join him and his Death eaters on the dark side, so you both got forced by your parents to become Death eaters, it was a hard time and it took a toll on the both of you mentally
months into you serving Voldermort, theo couldn’t do it anymore, he just felt horrible for the things he were doing to other people, so he became a double agent and sided with Harry Potter and Dumbledores army, but eventually he got found out by Voldermort, and the one thing he hated more than Harry was a traitor of his own kind…
so one night he decided to use some mind control spell on you, one that made you turn on Theo, your favourite person in the entire world, you became something entirely different to what you once were, and the worst part was Voldermort got you to tie Theodore up and threaten to kill him in the name of the dark lord
He looked up at you with pleading eyes, full of love, tears and pain, you threatened him with your wand to his throat, this wasn’t you, you would never even dream of hurting him, but you were … “Please, my love… don’t do this- this isn’t you, it’s him!… please, I love you!, I would let the world burn for you, Vara!, I would sacrifice everything for you!… we’re in love…” Theo pleaded, his voice full of passion and love for you
