Blackbeard vs Shanks incoming. If the world government be confortable to send two God Knights to Elbaph, its means Shanks are busy now. And what are Shanks group searching in the last painels? Teach.
The government only sent Shamrock (late Shonks, pranks danks tronks stonks scanks....) to Elbaph because they know Shanks is busy. At that moment, Shanks went after Teach, taking advantage of the fact that he is weakened after his recent events, and his nakamas too. The government will use Teach to take down Shanks, so that Shanks does not wage a war to free Elbaph. While the BB pirates are fighting against the redhead's pirates, the redheads will probably be winning, but then the 10 god knights will arrive through the pentagram teleport. We will have Garling and Teach vs Shanks.
JUST FOR THE RECORD, I DON'T LIKE THIS LOL. With Shanks out of the way, maybe we will receive the news at the end of the arc and maybe Elbaph will become Luffy's territory, and Luffy will go straight to Hachinosu....
