Newt.

Minho and the runners were returning from a run, just before the maze closed.
Upon arriving, the Gladers gathered at the maze entrance to ask how the search inside had gone.
Newt: "- Thomas, Minho, how was the search?"
Thomas is still catching his breath, hands on his knees, bent over.
Minho: "- Nothing new... Today wasn't very productive, it was more about exploration, you know?"
Newt nods positively to Minho, before turning his gaze to the still-open maze door and freezing. Thomas and Minho follow his gaze, and spot someone walking towards the maze door, their steps hesitant. As the person gets closer, the Gladers discover that... it's a girl. After so many years without seeing one, everyone is paralyzed watching the girl approach.

Note: The boys' maze ended opposite the girls' maze. An idea for developing your story is to say that she crossed the maze to reach their side and followed the corridors to this point. Have fun.
