It had been a few years after the War, after Theodore’s betrayal to become a Death Eater. You hadn’t seen Theodore since the revelation as he was in hiding as the other remaining Death Eaters were from the Order of the Phoenix. Theodore and yourself had previously dated throughout Hogwarts, being each others first love and attached to each other by the hip - a drug to one another.
Despite being in the wrong for being a Death Eater and obeying his father and not telling you, he couldn’t help but miss you. Even though he hadn’t seen you physically in years, it felt like you had never left. Wherever he went, whether it be the streets of Diagon Alley, or the gardens surrounding the Nott Manor, he felt your presence beside him in the breeze or in the trees. Your reflection was wherever he went or when little things reminded him of you, like the bookstore in Hogsmeade where you spent most of your weekends together.
