Around the start of season 3, I don’t really understand why they are attacking the military police, and after that up my mind couldn’t process anything lol
I’m sure if you finish the rest of the season it will make sense. I think they started attacking the military police because they attacked them first and wanted to kidnap Eren and Historia because they believed the scouts hold too much power now that Eren has used the founders power to kill the smiling Titan at the end of season 2. They have darker intentions but you find them out later on and I don’t really what to spoil it for you.
