BISP Ending Prediction (22/2/12)

I feel that there are several possible endings for the characters in The Boy In Striped Pyjamas

Bruno
-He goes back to Berlin and leads a normal life
-He stays in Out-With and continues being a friend with Shumuel, but I think something will happen and the relationship will either end or continue
-He discovered the horros of the camp

Gretel
-She goes back to Berlin and leads a normal life
- She discovers the relationship that Bruno and Shumuel has and either tells other people or keeps it a secret

Mother
-She goes back to Berlin and leads a normal life
-She has an affar with Lieutenant Kolter

Father
-He continues working for the Nazi's
-He withdraws himself from the Nazi's

Maria
-Follows the family back to Berlin

Patel
-Presumely dies in the camp
-Continues working in Out-With

Kolter
-Goes to Switzerland to stay with his father
-Continues working in Out-With

After Chapter 18 Update:

I feel that Bruno would discover the horros of the camp when he and Shumuel look for his papa, or perhaps he might end up getting trapped in the camp and no one would know eher he went and he may end up as a Jewish prisoner and presumedly be trapped there for the rest of his life or dies. The rest of the characters remain the same.

After Chapter 19 Update:

Bruno and Shumuel accidentally entered the gas chamber when a gassing was taking place. Bruno and Shumuel  and the end pages is confimed dead due to the toxic gas that was released into the chamber. The rest of the characters remain the same.

Afer Chapter 20 Update

Several months later, they are still looking for Bruno and Mother and Gretel head back to Berlin. Father decides to go back to the scene were Bruno's clothes were found and found that the base of the fence was not properly attached, his mind came up with a horrifying conclusion that Bruno had wandered into the camp and died there. When I read this, I was shocked and a bit emotional that the main character a little boy of the Commandment who still had so much to offer, died in a Nazi gas chamber which gives a sense of irony
