In the film, Warm Bodies, R tells Julie that she must wait a few days until the zombies forget that she is around before trying to escape. I understand that R is crushing on Julie at this point and would like very much for her to stay. I also understand that he is really trying to keep her safe.
However, when they first sneak out and begin driving the car around the airport for something to do *out of boredom*... why do they not just haul ass right then and there? I mean, they were able to get to the car unharmed, it would have been the prime opportunity to just take off. Instead, she ends up sticking around for a few more days. She obviously didn't have to stay.
