Continuity mistake: Dio is gloating thinking that JoJo probably got himself killed in Ogre Street already. A crowd of disreputable individuals zombie-walks towards him; one of the guys in front has some sort of scythe that he holds in opposite directions when we switch to the reverse angle. (00:15:55)

1 continuity mistake in Kako kara no tegami
Starring: Matthew Mercer, Daisuke Ono, David Vincent
Continuity mistake: Dio challenges some hoodlum at the game that men of dubious virtue would play in the London slums at the turn of the century; chess. He reaches over to grab the coins the guy tossed at him, but when the sore loser smashes his face in the grub, the dish is suddenly directly in front of him and the chessboard disappeared. (00:03:10)
Jotaro Kujo: Yare yare daze... Good grief.
Trivia: Dio in this episode drinks Cronenberg Whisky, just like in the manga. The fictional brand is most likely a homage to the director David Cronenberg, especially given the bit of 'body horror' appearing in this arc.
