The scene with Alucar, is authentic, not an illusion. It is during the attack of the brotherhood of the castle (remember the trailer).
About the end. Enric Alvarez is a fan of Japanese anime, do not expect an end "Disney" is a story about evil, will be tragic. You saw the first.
And remember that with this release dies this timeline, so what happens to the characters is not very important (there will be no more future, although maybe if passed).
