Fridge / Resident Evil 0

  • In a manner of speaking, Marcus does posthumously gain revenge on Umbrella; his leaking of the T-Virus in the mansion sets the wheels in motion for everything else that goes to hell after that. Eventually, Umbrella's actions do become public knowledge and they soon fold. Ironically, his actions set the stage for an even worse monster to rise, a monster that ironically was one of the two men that assassinated him, Albert Wesker.
  • The helicopter crash at the beginning - it's very likely that Wesker had it remotely set to break down in the Arklay mountains / testing area.
  • Billy's fate is both Fridge Brilliance and Fridge Horror. At the end of the game, he heads in the opposite direction of the Spencer mansion with a magnum revolver and 5 rounds. Since he's an excellent marksman with a powerful weapon heading away from the zombie infestation, he almost certainly got out of the forest in one piece. The Fridge Horror sets in when it's never revealed if he made it out of Raccoon City before it got nuked.
    • Given that two months pass in between the events of 0 and the destruction of Raccoon City, it's a safe bet he made it out.
