10 Unanswered Questions From Resident Evil 7
2. How Was The Ship Still Running Three Years Later?
The ship tape sequence shortly before Mia is infected takes place in October 2014, but when the player returns there in the present portion of the game, it's now mid-2017. Considering the ship presumably hasn't been tampered with, how exactly is the ship still operational with fully functional electricity?
The Likely Answer: You can conjure up some real mental gymnastics to make this one work within the context of the game (perhaps it had nuclear power typically reserved for military ships), but there's no real, logical answer beyond "because reasons" and "because this is a silly horror video game."
Granted the ship section of the game is probably its flimsiest and most drawn-out sequence, which gives you a lot of time to think about odd inconsistencies such as this.
