Well, this was an interesting set up chapter,

With both Jacob and Ajeel's fights, it is quite understandable how they lost, probably since they were far injured or used too much energy. And Jacob while closing his eyes can use some sort of extra sense to attack was still weakened from his previous fight.

Well I guess either Ajeel was still too injured or weakened from his fight with Erza so that allowed the siblings to defeat him, but that was an interesting scene, trying to mend the tension between nations.

it looks like there might be peace between nations at the end of all this.

it is interesting to see the fight between August and Gildarts, the Spriggan 12 managed to do some crazy shit throughout this entire arc we finally get to see how strong August is.

i wonder what Gray's trump card would be, maybe it is Memento Mori that he absorbed back in Tartaros and would use it against Zeref since it was made to kill him.
