I wanted your opinion on predictable plot points. Let's pretend that a plot centers on an orphaned teenaged girl that travels to the past to see her parents when they were alive. She doesn't tell the two other main protagonists that she is their child from the future. Instead, she just pretends to be a stowaway on their ship. However, as the book progresses, she leaves the readers clues such as knowing her way around a ship that, for all intents and purposes for the crew, she has never been on. She acts like she knows various other characters. Somewhere in the climax, she reveals by accident that she is in fact their child and she did, in fact, know this ship because...she's the captain of it in her future. Something like "Of course I know this ship, mother! I'm the captain of it!" while the two are trying to steer the ship away from enemy fire. Now, my question is: How would you disguise all of that so the readers won't say, "I knew this was coming from Page 1." Is it possible anymore, given the many, many times we've seen variations of the "I Am Your Parent/Child" deal? Discuss!
