"Allegiant - Part 1" will reportedly introduce a new character David, who is part of the Bureau of Genetic Warfare.
According to Fashion N Style, it is highly possible that a David storyline will be part of the movie because it was a crucial part of Veronica Roth's book.
Additionally, the Bureau of Genetic Warfare in general will also have a huge impact on the lives of Tris (Shailene Woodley) and Four (Theo James).
Meanwhile, the publication revealed that there are two other storylines from Roth's book that should be part of the movie. This includes Tris and Four's first date and a scene that will feature Tris reading her mom's journal.
Both scenes from the book have been iconic because Tris and Four's date is a memorable part of the characters' story. Tris reading her mom's journal will certainly tug at the heartstrings of the audiences and make them cry.
However, even though the filming for "Allegiant - Part 1" has already concluded, fans still do not have any idea which scenes from the book will be part of the movie.
Lionsgate has not yet confirmed or deny the speculations mentioned above. What is only known as of the moment is the fact that Tris will die in "Allegiant." In the book, the character passed away after saving the rest of human kind.
In an interview with MTV News, Roth said that it is important to kill off the character in the film because it's part of Tris' fate.
"Allegiant - Part 1" is slated to hit theaters in the United States on Mar. 18, 2016.
