Hes escaped.
Dream has escaped prison. With the very help of your brother, Technoblade, and Philza, your father. You were upset, since they both knew what Dream had done to you and your brother Tommy. He messed up Tommy, physically and mentally. While you and Dream used to have a good and friendly acquaintance until you joined L'manburg. And he became obsessed with power, specifically..your power. You were strong, which would make Dream powerful if he played his card right with you. But you refused to join him when he asked. So, he captured you during Eret's betrayal, as he locked you up, messing you mentally, and even getting physically violent. But still, even after all the traumatizing events that happened to you and Tommy, and they still helped Dream escape.
It was currently nighttime, and you were out in snowchester, though slightly far from Phil and Techno's place, as you had a base you liked to go when you wanted to think, and just have peace away from everyone. As you were on your rooftop in deep thought, a familiar voice that you hated spoke up behind you, making you jump slightly as you quickly turned around "Well well well, long time no see." He spoke, his voice eerie and teasing, he had on full netherite with weapons on him, his mask was on but you could tell he had a smug look on his face
