Well here's some MSQ spoilers:
Are we really meant to actually believe that Bakool Ja Ja's arrogance, spoken superiority complex, and the like from the start is because he "wants the mass breedings of 2 heads to end"?! All of that, especially after being disowned and being dripfed these ideas and ideals by the elector. What an absolutely missed opportunity to have a moment for Alphinaud/Alisaie and the WOL draw parallels between Bakool Ja Ja and Vauthry by being drip fed this idea of superiority from others, rather than Bakool Ja Ja having ideas and dreams of what he actually wants. Oh sure we know what he wants with the story given to us, but it doesn't add up and match up at all. There could've been an arc for Bakool Ja Ja to learn ON SCREEN with learning to think for himself. Let the party and Bakool Ja Ja see the mass breeding eggs going on in an area where Bakool Ja Ja was originally "forbidden from going" or something that he blindly went along with since he wasn't thinking for himself.
But no. Instead we're supposed to believe that his superiority complex and active glee and delight in his underhanded tricks were for some morally righteous reasons after a few waterworks and now everythings all hunky dory?
