Bella managed to get to the camp, she didn't try to use any sneaky method to gain entry and walked right through the front gate with her hands above her head.
She knew that time was of the essence and the longer she waited, the probability that she came here in the first place was in vain.
She had planned to wait out the night but she also knew that this was a recipe for disaster, she couldn't risk it because she didn't know what lurked.
The people there were shocked to see her but Bella was surprised that she wasn't treated as hostile, the people that welcomed her cheered.
This confused Bella considering she had betrayed them but this only made her put her guard up.
There had to be some sort of ulterior motive to this and she wasn't going to let this disarm her.
Bella smiled and the weapon she had on her wasn't taken away at the entrance.
