JoJo’s Bizarre Adventure: Steel Ball Run Episode 6 ended with Johnny’s left arm being ripped open from the inside, and Episode 7 has the decency to explain why. The short version is that his arm is changing because a mummified chunk of the Saint’s Corpse has fused into his flesh, and Tusk is the Stand that climbs out of it to save his skin.

The long version involves a map, a president and an assassin whose Stand fishes people out of the desert. After a week spent in Gyro’s tragic past, the story snaps back to the dust and starts hurting people again. The episode hands Johnny a miracle and then sends someone to kill him for it.

Why Is There a Mummified Arm Growing Out of Johnny?

Because Johnny has become the unwitting host of the Saint’s Corpse’s left arm. It fused with him without him noticing, and Episode 7 finally lets us watch it happen, with a mummified arm emerging from his own left arm and sinking into his flesh.

The joke is who gets blamed for it. Funny Valentine is convinced Gyro stumbled onto the relic, and Oyecomova has already flunked the job of killing him, so the president sends Pork Pie Hat Kid. His Stand, Wired, hauls Gyro off on winch-driven hooks and leaves him dangling in mid-air like a coat on a peg, blood dripping steadily onto the ground.

Johnny, meanwhile, works out that the Kid isn’t only after Gyro. They want whatever is fused inside him, and I’ll admit there is something deliciously unfair about the sidekick holding the prize without knowing it.

What Is Tusk in Steel Ball Run?

Tusk is Johnny’s Stand, and what we see is its first form, Tusk Act 1. It’s the guardian of the Corpse’s left arm, which is why it emerges from his. Close to death and channeling the Spin Gyro has been drilling into him, Johnny gets his fingernails whirring like drill bits, and Tusk steps out of his arm to meet the occasion.

That is the Spin applied to his own body, turning fingernails into projectiles. It’s also only the starting form, since Tusk evolves through further Acts over the story.

Then Tusk whispers mysterious words Movere crus, which even Johnny cannot yet comprehend. In literal terms, Crus is Latin for leg and movere means to move, so it roughly translates to move the leg, a pointed message for a man who can’t walk. I’m wary of overselling a guess, and we haven’t found anything official confirming it.

What Does Valentine Want With the Saint’s Corpse?

This is the real reveal of the episode. The narrator opens with Joseph of Arimathea, the man said to have taken Jesus Christ’s body down after the crucifixion, and a mysterious map tied to him that marks locations across a continent nobody knew existed yet. That map now belongs to Valentine.

So the $50 million horse race turns out to be a continent-wide dig, with the racers unknowingly galloping past the spots where the scattered relics lie. Whoever holds them gets power, luck and authority, which explains why Valentine treats one stray jockey with a piece as a national emergency. According to The JoJo Wiki, the number of parts are nine.

Steven Steel objects when he realizes Valentine wants Gyro dead and doesn’t care how many others die. Valentine answers by showing him the map and ordering the race to continue. There is no debate, which is the scariest part.

Steel Ball Run Episode 8 should arrive Friday, November 6, on Netflix, with Gyro still dangling and Johnny’s brand-new Stand on the clock.
