I have a Prologue set 30 years before my Main Plot. A major plot event occurs in the Prologue that sets in motion all that happens in the 30 years between the Prologue and the Main Plot--as well as everything that happens in the Main Plot itself. (I would do away with the Prologue altogether except that it introduces essential elements of the story and the beginning of the two Prologue characters' motivations that I don't believe can be introduced later.) There are two characters in the Prologue, an adult master and an child apprentice. (This is going to sound very Obi-Wan and Anakin, if that helps.) Both characters are major characters in the Main Plot later. Neither is the hero. One becomes the Villain. Here's my issue: Right now the character in the Prologue that I have slated to become the villain in the Main Plot (but isn't yet) wants to turn on a device. Call him Bad Guy (or BG) to keep this simple. At the same time, the character in the Prologue that I have slated to become a good guy in the Main Plot (but isn't yet) wants to destroy the device. (He knows that the device can bring about good or evil, but this is what scares him. The reader doesn't necessarily need to know this, of course. This is part of what I'm asking below.) Call him Good Guy (or GG) to keep this simple. The problem is, I think it's important that it remain unclear to the reader: 1) whether turning the device on or not is good or bad. (I think I mostly have this part right, if that matters) 2) whether the future Bad Guy, in wanting to turn on the device, is doing good or evil by doing so. If anything, it should appear he's doing good here. (I think I have this "kind of" right, because I make it seem like it may be a mistake--even from his perspective--but also he overwhelmingly thinks he should and wants to turn the device on...and so does the reader/audience.) 3) the real motivation for the Good Guy wanting to destroy the device. In other words, it should be unclear to the reader: Is the future Good Guy doing evil...or good here? If anything, it should probably look like he's doing evil here. Am I, the reader, seeing a glimpse of the future Villain here? (Which, of course, they're not.) #3 is where I'm really struggling. The reason #3 matters is simple: I don't want to give away that future Good Guy is the same character in the future when we see him 30 years later; and that the future Bad Guy is the villain. This will be revealed late in the book via flashbacks. They need to remain mysteriously ambiguous in the Prologue. I am looking for plot (or character) devices to make this happen. (This may be better asked in Character Development, so if so, please let me know as I'm a noob on this site. My instinct is that there is a plot trick I can pull here though to sort of misdirect the reader.) My problem with #3 is that both of my alpha readers said essentially: "When reading the Prologue, I knew that the future Good Guy was exactly that. I knew that--even though you made him seem like a cold jerk to the future Bad Guy--he was destroying the device for a good reason. "After all, future Bad Guys don't destroy devices. They use them for their evil plots. "Only Good Guys destroy devices that may bring evil." (So maybe I need some sort of way to misdirect the reader's thinking, perhaps?) Right now, the Prologue (but not Main Plot) is told third person from future Bad Guy's viewpoint/perspective if that matters. I'd appreciate any help I can get, because I'm stumped. An above-and-beyond answer might answer the question(s) posed based on whether: A) the apprentice becomes the villain and the master becomes a good guy (like Obi-Wan and Anakin) B) the master becomes the villain and the apprentice becomes a good guy (how would the answer change if Anakin had stayed good and Obi-Wan had turned to the dark side?) As of right now, I'm writing more towards "A" here, but open to other ideas or even incomplete answers that may spark an idea. Book Information: This is for a children's mid-grade fantasy novel, but the Prologue scene itself is not at all fantasy. It's being written for perhaps 8-12 year olds with 11 year olds as sweet spot.
