Existem dois cenários que eu li na Internet no Joker / Gambol do Cavaleiro das Trevas: "Por que tão sério?" cena.
Coringa matou o Gambol . Há um FAQ do IMDB intitulado: Como exatamente o Gambol morreu pela faca do Coringa? . Afirma:
There is a belief among some fans that you can't die from having your cheek slashed, but it is possible; laceration of the face was listed as a cause of death in the infamous Black Dahlia murder. The shock and blood loss could cause death. It's also possible that the Joker got carried away and went beyond cutting Gambol's cheeks. Since the murder happened off camera, we don't know.
Coringa matou o Gambol . De um artigo da Wikia sobre o Gambol :
After placing a bounty on him, Gambol was tricked by a trio of bounty hunters who made it seem like they brought him the Joker dead. The Joker revealed himself alive after stabbing two of Gambol's men with knives, pressed a knife in Gambol's mouth, and told him an ambiguous story of how he got his scars, before killing him with the knife.
Some claim that Gambol survived his attack by the Joker and can be briefly seen later in the film being arrested during a GCPD on his neighbourhood. This claim is disputed by many though as it would render the narrative purpose of the Joker's visit to Gambol's headquarters useless (if Gambol had lived it would be unlikely that the other mob bosses would have hired the Joker).
O recém-lançado livro dos bastidores da trilogia confirma que Gambol foi de fato assassinado pelo The Joker.
