Faith lied down on the mucky cave ground, her vision was about to start.
I'm very sure! Just watch me.
In her vision she saw Uncle Miles and Mrs. Lambent talking. She was hiding in a bush far away, but close enough to hear them talking. After they were done talking Faith learned that Mrs. Lambent was the one looking for the Lie Tree and she was the real scientist, not her husband. And the only reason why her family was here in the first place was because Uncle Miles wanted to be part of the dig, and the only way for him to do that was if her father came with him. There plan was working, Faith couldn't let that happen anymore. She needed to stop them, some how.
You were sweating and cry a lot.
She told Peter what happened in her vision. They both were surprised. Faith felt like she was the one responcable so she told her mother all about Uncle Miles. They then decided to escape the island. They made it out safe and sound.
