The City of Ember: Chapter 14

In chapter 14, The Way Out, Doon and Lina went to investigate what they thought was the exit. They had found a latter leading down to a dark, dark space. They found a door, leading into an even darker room. In the room, they found 2 boxes of tools labeled *"Candles" and *"Matches", and some kind of thing labeled *"Boat". After they found out what they were for, they found a river: their way out.

*They don't know what it is.

QUESTIONS: Do you think they'll tell the rest if Ember? Will the rest of Ember believe them? When will they go?
