Rachel and Bella were trying to stay out of sight because they knew that the men in these walls weren't the only enemies that they had to worry about.
They also had to worry about the zombies roaming outside, Bella had no intentions of escaping but one could say she returned here to retrieve that item that happened to be with Liam when she arrived.
"Are you going to kill me?" Bella asked Rachel directly.
"I don't know, I have never killed anyone before but I know I wouldn't feel guilty if I killed you," Rachel said and this brought about a weak smile from Bella.
She expected this answer but it stung a little because she thought that Rachel and her were getting along.
"That is harsh but your feelings aren't misplaced," Bella said, she could have easily lied to Rachel and kept this fact buried.
Bella was tired of the lies, it was exhausting and she just wanted everything out.
