Overdrive (Episode)

"The harsh wind blowing down over the Arctic Ocean birthed the fearsome Vikings. Only when we are tossed headlong into the crucible of adversity do we rise to the challenge. What will a glass of vino create this night?"

Jonathan focuse onto his wine glass and realizes he can draw out the power of the ripple using the ripples in the wine. He charges up a sendo ripple overdrive and punches a wall nearby.

Jack is hit dead-on and flies backward into the opposite wall and disintegrates.

Manga/Anime Differences

 * The anime started with Speedwagon's second time entering the hospital. The first time was not shown, with Speedwagon in a wagon with his friends. When Speedwagon tried going to Jonathan's room the first time, he is coldly turned away by Erina and decides to return later.
 * In the manga, he sneaks in over a wall with his cane when he visits for the second time. He also attempts to enter the room after Jonathan awakens, only to change his mind after Erina says Jonathan's name.
 * In the manga, Jack is first seen conversing with the woman he kills, talking about Jack the Ripper and revealing that she's been talking to him before stabbing her.
 * In the manga, Dio was stabbed by Jack the Ripper multiple times before he decided to join him. In the anime, Dio used some type of mind control and Jack was instantly subdued.
 * The flashback explanation of how Dio escaped the mansion alive (the pillar near the statue broke and destroyed the statue Dio was impaled on) was not in the anime.
 * The arm that Jonathan heals is reversed in the anime.
 * Zeppeli's first appearance garments from the manga are replaced by his second usual ones.
 * Zeppeli's shaker breaking and causing him to sneeze more is cut from the anime.
 * Zeppeli explains that he overheard Wang Chan discussing the Joestar Mansion fire and Dio in town, and subsequently went to meet Jonathan. His convenient arrival is not explained in the anime.
 * Zeppeli does not explain the Zoom Punch after he hits Jonathan with it in the manga.
 * Zeppeli's flashback has slightly more detail in the manga, also showing how he attempted to escape with a crew member, only for the crew member to be killed.
 * In the manga, where Zeppeli compares the Ripple and the Stone Mask, he throws one pebble while Jonathan throws the other. In the anime, Zeppeli throws both.
 * The battle between Jonathan and Wang Chan a week after Jonathan is told about Zeppeli's past was not shown in the anime.
 * Since this battle is removed, Wang Chan does not tell Dio about how he fled, and Speedwagon does not flip into the carriage talking about how Wang Chan was seen at Windknight's.
 * Two gossiping ladies talking about how someone's moved into the mansion by the graveyard is cut from the anime.
 * Zeppeli asking for a corkscrew is cut from the anime. Speedwagon also saying how he wouldn't want to see through the eyes of Jack the Ripper and Zeppeli quieting him is cut.
 * Jack does not cut off part of his thumb in the anime. Zeppeli is also much more surprised that Jack would throw the wagon at the entrance in the manga.
 * During the battle with Jack the Ripper, Jack launches a bunch of knives out of his body. In the manga, Jonathan and Speedwagon hide behind a rock. Speedwagon is also cut in the shoulder by one of the knives. In the anime, they do not hide, and Speedwagon is not harmed.
 * Zeppeli also gives an explanation as to how his Ripple Cutter works in the manga.
 * After Jack is hurt by Zeppeli's kick, one of his eyes is crying in the manga.
 * When Jonathan is injured by Jack, the device Jack uses is thought to be a remodeled torture instrument from the Middle Ages by Jonathan in the manga.
 * In the manga, Zeppeli told a story to Speedwagon about a fisherman who cut his own leg to attack a shark and kill it. In the anime he never told this story.

Commentary
"The Ripple is here! You also find the famous onomatopoeia "Memeta" when the frog is punched. The episode necessitated more effort for the photography and vector graphics than the animation; it was a small challenge for those who weren't used to them.

It's also the arrival of Zeppeli, conveying his eccentric side at best was necessary. More and more dangerous characters like Jack the Ripper make their appearance. Jonathan and Erina have again a languid scene (laughs). I also like the scene where Jonathan's arm is healed thanks to the Ripple... "I can even lift this rock!" It wasn't planned in the storyboard but honestly, it had to be here even at the risk of upsetting everything. The audience had to see how awesome the Ripple is. The voice acting was also a great moment, everyone was excited like in those overnight infomercials."
