In Transformers: Revenge of the Fallen: Movie Prequel: Defiance Volume 2 the Autobots and the Decepticons are philosophically divided over whether they should continue their passive ways or aggressively attack those who attacked them.

This is issue number 2 of four. There is a very short summary of the previous episode on the title page before the graphic novel begins. I almost missed it. True graphic novel readers, might not have this same problem. True fans would probably not have any trouble telling the Decepticons from the Autobots, either.
