I'm going ahead with a story series I wanted to start off with a flash forward showing the MC twenty years later. I'm doing this because I originally intended for this story to be a prequel, but due to its actual length I thought writing it first would be better. I wanted to start off the first story with a flash forward of showing who she has become and will be in the sequel series. I'm not going to be showing much and I don't intend on revealing it's the MC, but there's some events that I want to show her adult self reflecting on before they actually happen as well as probe her more experienced mind a bit. However I'm worried that this could potentially spoil the suspense in some parts of the prequel. Including parts where her ass is on the line or her life is in danger and I don't want to entirely ruin those moments by eventually revealing she's gonna live anyway. Would it be smart to flash forward anyway as foreshadowing?
