Im not sure whether it was intentional, but I didnt get it. At the end it seemed that she struggled with something, then she placed the sheriff badge near the corpses and then she could stand again. And then she looked at the tape on her arm and said “theyre good at supplying”.

What was is it in the end? Did placing the badge jam some sort of signal that shouldve killed her? Or were the usual tapes bad on purpose, and they gave her one that in fact seals the suit?
