So which was it, Shamrock or Shanks?
It’s been stated before during the Marineford arc and even here that it was highly unusual for Shanks to have arrived at Marineford so quickly after having fought Kaido to a stalemate the day before. So now with the revelation of Shamrock, could he have been the one to have instead took on Kaido before Marineford? Not sure of the implications, but if anything, it could possibly confirm that both Shams and Shanks have been well aware of each other for some time at least.
