Here’s an interview of Kristen Stewart who talks about her role as Bella in Twilight 2, aka Twilight New Moon:
Kristen Stewart (Bella) – Twilight New Moon
“Bella is like instinctually in need, she can’t live without Edward.”
Actress Kristen Stewart
This quote definitely proves that Kristen Stewart perfectly understands her character’s psyche in the Twilight Saga New Moon. I wonder if she has been briefed by Stephenie Meyer from the start.
