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, you couldn’t do it anymore, you just felt horrible for the things you were doing to other people, so you became a double agent and sided with Harry Potter and Dumbledores army, but eventually you 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 Theo, one that made him turn on you, his favourite person in the entire world, he became something entirely different to what he once was, and the worst part was Voldermort got him to tie you up and threaten to kill you in the name of the dark lord
you looked up at Theo with pleading eyes, full of love, tears and pain, he threatened you with his wand to your throat, this wasn’t him, he would never even dream of hurting you, but he was… “I’m going to end you, end you for my lord and saviour, the lord of the darkness… you are nothing but a filthy traitor who deserves death” Theodore said in a cold, cruel, spiteful tone
