Ppl not mentioning much about Davy jones.....
It's a Davy jones upscale chapter.
Imu target Xebec because he is connected to Davy jones and even calls him with the name.
Same way "why did you let Joyboy(Luffy)escape" to Saturn before he kills him.
Davy jones and Joyboy are 99% rivals too as a pirate in those era with common enemy aka Imu
