- Despite taking place in Brazil, where the primary language is Portuguese, this issue's regional characters speak smatterings of Spanish. While Spanish was historically an influential language in the history of Brazil's Acre state, the predominant language today has long been Portuguese. It would be unrealistic for every local character encountered to speak either only Spanish or English with smatterings of only Spanish, as this issue portrays them.
