I really like this chapter, it is satisfying how they all come out clear and finally resolve their conflicts and diferences.
The climax of the story is not when Eren becomes the founding titan, it is not when the hidden stories of the past are revealed, is it not when they have these awesome fights, it is not when Eren either wins or loses, not even when we get to see why Eren was crying in chapter 1.
The true climax is the page 31 of this chapter ^^/
