It did. It's a shame that King didn't get more focus in the manga. He has an interesting backstory, which has some implications for the future (Seraphim, etc.), so it could have been fleshed out a little more.
It's insane how much care was put into this episode, especially as it's all done by hand. It's almost too much. I can't even imagine what the remaining Luffy vs. Kaido fights are going to be like.
