What are the changes for Luke when he gets to know Jen?

Luke gravitates towards Jen's idealism and passion for acting on what she believes. In turn, Jen teaches Luke that like her, he has inalienable rights.... freedom to live. Luke also learns about patience, the difference between Jen's impetuous actions, and what might have been had she taken more time to plan.... had a bit more restraint. The most important change in Luke's life, however, are the things that Jen taught Luke about himself. She inspired him to move on.... and to create change.
