Headscratchers / JoJo's Bizarre Adventure: Eyes of Heaven

• How can Dio Brando and Diego be in the same area without exploding? Same with Jonathan and Johnny.
  • The in-game explanation is that anything brought in by Valentine from another universe will explode on contact with its counterpart. This does not apply to time travel, as that still counts as "the main universe." According to the game Dio, Diego, Jonathan, Johnny, Joseph, and Joseph are all from the "main universe" and thus do not explode.
    • maybe it's the nature of their meeting, since Filthy Acts isn't involved they can touch each other however they want, since Heaven ascension DIO got to the game's dimension through D4C he is affected through contact with other versions of himself
    • The best answer to this I could think of is that they are not 'exactly' the same people. For example Jonathan was born in 1868, Johnny was born in 1872. Thus they cannot be the same person. Same goes for Dio and Diego, born in 1867 and 1870 respectively. Since they are not the 'Same' person only similar, they don't cause the duplicate explosion.
• Where was old Polnareff? Maybe I skimmed something but shouldn't he still be conscious in Coco Jumbo?
  • Old Polnareff doesn't actually appear in the game but the Vento Aureo gang do reference him when they meet normal Polnareff.
