Hey what's up. I am new here but I think i can explain this. From watching the previous seasons and this one I have determined that Adam was promoted to second in command over Rocky. When Rocky was second in command, it seemed more like Adam took charge more then Rocky and Adam in my opinion would make a better leader. It is possible Zordon saw this as well. Thus demoting Rocky and promoting Adam. Of course this is all prior to Jason showing up. How the ranking structure might have changed there, i am not entirely sure if Jason become second in command or if Adam remained second in command.

Edit: forgot the main point in me posting. lol. That was with the quotes one. They put them in that order cause of their helmets. Which is something they really could not change. lol.
