- 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.
- Thanks to this game, we finally get an explanation as to why Rebecca does so little over the course of the first game (at least when compared to how much Barry does for Jill): she's been awake for at least a day and a half, fighting for her life the entire time, and now she's stuck in the mansion, doesn't know where her team is, Billy is gone, and she is absolutely exhausted.
- 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... but 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.
- Given how everyone, including the Bravo team, was quick to believe Billy was the murderer he was convicted of being, with ONLY Rebecca knowing of his innocence due to her experiences with him, it would seem likely that, if he did survive, he would have went into hiding. Billy makes a point to tell Rebecca that he has a choice to either report to the Marines to be executed, or stay on the run for as long as he can. It's highly unlikely he stayed in Raccoon City. He probably would've headed for Mexico.
- Fridge Brilliance: The inversion of Selective Memory is easily explained as Gameplay and Story Segregation. Rebecca and Billy have radios they use to stay in radio contact throughout the game. Although they're only seen using this in cutscenes (or when Rebecca is at the risk of falling to her death in the sub basement), the obvious logic is that when you switch over to a character to perform a specific task, the other character is radioing them to tell them what to do and to provide needed information. It's just not shown in the game because that would slow things down and require extraneous coding that the game's engine just can't handle. If the game had done this, in addition to being tedious for the player, it would've fallen into another trope.
- This is actually shown and somewhat supported in the novelization. While they do not use radios quite as often, Billy and Rebecca are shown to be cooperating, sometimes even on different floors and in different rooms from each other, in order to progress through the puzzles. Thus, while the game does not show it, it would seem likely that this is the case in-game as well, though using the player as the medium instead.
