I this part of the scene everyone is gathering around the create because the alarm has sounded. Everyone is curious to why another person is coming already.
This scene has a strange effect of the story because the people in the Glade only get one new person a month. Although in this scene, the Glade get two new people in just two days. This leaves the reader in suspense because now we are unsure why this girl came the day after Thomas and showed up half died. In addition to, she is the first girl to ever come to the Glade.
The new girl said, "Everything is going to change." This leaves the reader intrigued, we now know nothing about what the girl meant by that statement. She also held up a piece of paper stating, "She's the last one. Ever." This means no one else will be sent through the create. I choose this scene because it leaves the reader thinking about what will happen next.
