For context, Lizzy used to be Blitzen's girlfriend, and used to be one of his only sources of consolidation in a world full of people that bullied and hated him. She was always there for him, even in his lowest times, and was just all around an absolute sweetheart. However, after Blitzen briefly went insane and killed both of his parents by gunshot, Lizzy was disgusted by what Blitzen did and left him, refusing to forgive him despite his extreme feelings of remorse over his actions, and he never saw her again… leaving him all alone… and although Blitzen may have Camila now, he still sometimes feels his eyes well up with tears when he remembers the times when he had Lizzy… the times when he was kind and happy.
