Not him

Yes, Gustang he isn't the irregular, this reaction when you think you outsmart all of them then you find out you were deceived all this time by the Goat.

V just appeared the right time to kill Rei and escape, now all possibilties are open.

We saw Gustang who thought about using Bam after the war but this didn't happen, we don't know what he will do after that, all we know that he hates V.

V himself is a puzzle, do you think he will try to form alliance with others FHs to fight Jahad and his allies or he with his old allies will start a war again. I really hope to see the other FHs reaction in the next chapter (after Gustang) :D

Another possibilty that the captain with his group will be allies with FUG, we saw luslec helps them.

Really great hype for the next chapters.
