My son is riding me because I actually felt badly for her being basically given a death sentence on Narkina 5, or wherever.
Dedra was a monster, as Denise Gough has stated, but OMG she pulled at my heartstrings in that final shot of her. That's because of the actress.
We just also rewatched S1, and I remember that the face she was making was exactly how Andor looked on his first night. Like he thought about stepping onto that floor. But then it jumped ahead a month, and he was getting up for his day, had plenty of energy, and seemed to have connected with his fellow slaves, almost looking forward to working with his new group of friends. That's the mistake the Empire made, letting them bond, allowing them to think of themselves as a group, and not as individuals.
I would also wonder if they've changed how they operate since the big prison break.
