Jonas and The Giver decide that things have to change, so they think of a plan. Explain their plan.

The plan that the two of them dream up is that they are
going to do something that will destroy the way the community is currently set up.  They
are going to try to destroy the sameness that they hate so
much.

The way that they will do this is by having Jonas
escape to Elsewhere.  Once he leaves, all the memories that he has will somehow be
transferred to the minds of the people in the community.  We know this will happen
because that is what happened when the previous Receiver was released.  As the community
gets all these memories that Jonas has, their society will be forever changed because
they will understand about colors and feelings and love and pain and things like
that.
