Summary
Meanwhile at Dio’s castle Poco's sister is in audience with Dio himself. Dio proposes for him to turn her into a vampire giving her free choice but at this, she slaps him. Dio merely smirks at this and introduces her to Doobie who happened to be right above her as he leaves her and Doobie to do as they please. At this Doobie attempts to rape Poco's sister but from the skylight, an anvil falls on his head. Doobie looks up to see Jonathan and company.

Jonathan leaps to attack Doobie but then poisonous snakes emerge from his mask and they all bite Jonathan. After Doobie does this, he takes off his mask revealing the snakes to be growing out of his face! Doobie then goes to attack Jonathan but then Jonathan grabs all of the snakes and forces the poison out of his body with the Ripple. Then Jonathan sends a Ripple into Doobie's body that makes his snakes eat him alive. Afterwards Poco reunites with his lost sister and Jonathan leaves to find Dio in his castle, which he does.
