you and Sebastian both got sent to Azkaban 10 years ago, Sebastian for using the killing curse on his uncle and you for using crucio multiple times on Sebastian's uncle

you had both been stuck in separate cells, that was until today, Sebastian broke out and set you free, you had both been 15 the last time you saw each other, you were now both 25,it was torture only being able to hear each other for the past ten years and not see each other

you were both just staring at eachother
