Different POV?

If the Messenger had a different point of view from Matty's then the whole plot-line could change. For example, if it was from Seer's point of view, we would have known what he was thinking at times and why he said that Forest was an illusion. We also might have known a lot more early on in the story since Seer has a "special vision behind his ruined eyes" (Lowry, chap 1). Another example could be if the story was told from a 1st person point of view. Instead of having a more omniscient POV, we would only know what Matty is thinking and experiencing. This is very different because  in the omniscient view, where it shows Leader using his gift to look beyond. It foreshadows when it said, "He was very worried himself. He had not told the blind man. But while he had watched Matty, Kira and the puppy enter Forest, he had been able to see, too, that Forest was shifting, moving, thickening, and preparing to destroy them." (Lowry, chap 15). The meaning of the story could also change by having different themes being conveyed with different characters and points of  view. Over-all, the plot and meaning of this novel could change if the perspective/point of view is changed. 

This would be an example of a different POV!
