Question: How can they use the elevator to get to the surface if the Red Queen shut the power down?
Answer: The force of the water moved the elevator up the shaft, hence why it did not go all the way up.
Question: What happened to Chris and Claire Redfield? They aren't even mentioned in the film.
Chosen answer: They might bring them up in the next movie. Jill Vallentine was also lost for so many movies.
Question: Why in Resident Evil 4 when Alice takes the robotic bug off of Claire's chest it takes her days to remember who she is but when Jill has the same thing done to her she knows who Alice is in under 5 minutes.
Chosen answer: Jill was unconscious at the time, while Claire was awake, therefore the loss of memory may differ by state of mind, or vary from person to person.
Question: How do One, Rain and Olivera end up in this one? All of them were very thoroughly killed off and the end of their respective movies. Are they clones as well, and if so, why doesn't Umbrella just use new guards?
Chosen answer: Umbrella can produce their DNA's again and again.They use them because Alice acts mostly with her feelings and all these persons mean something to her.
Question: If Albert Wesker is the leader of Umbrella, why he cant stop Jill Valentine from coming after Alice?
Chosen answer: It's stated in the film that Wesker had departed Umbrella and that the red queen has control now.
Answer: She must have had trouble in keeping control of the elevator's power as the impact of the explosion blew out some of the windows and the sea came rushing in.
