On Assignment day Doon asked Lina to to trade jobs. Because Doon can not save the city when he is messenger. Lina got pipe works labour and Doon got messenger. This scene is important because if Lina and Doon would of found the door in the roped of tunnel.
Blue sky and goodbye
I am so happy we are not in a broken city!
In this scene Lina comes home to find granny tearing apart the closet and Poppy eating paper of some sort and a wrecked box with a mysterious lock. This scene is important because the box is what holds the instructions to something and the paper might be the clue to getting out of Ember anything would be better then this broken city.
We saved the city!!!
Lina wakes up to find that granny has past in her sleep. Now that Granny is no longer alive who will take care of Lina and Poppy has Granny fond what she had lost?
I predict that Doon will create a movable light and use it to get out of Ember. They will find a a city called Dreamlet with blue sky. And natural light that will last them more then two hundred years.Lina will be the new mayor and Doon will be real axing all there work has paid of.Two years later Doon and Lina miss Ember but do not whant to go back!
