The Host Theme of Memory and the Past

We are all affected by our memories. Memories can be tied to smells, places, and people. But what if you had someone else's memories? Would that change who you are? In The Host, both Wanda has to deal with a big memory mix-up. Initially, she's supposed to use Melanie's memories to lead the Seeker to the surviving humans. The problem? Melanie's memories are so strong, Wanda develops an intense attachment to the people in them, driving her motivation for the rest of the book. That's some pretty powerful stuff.

1. How do Melanie's memories affect Wanda's actions?
2. When the parasites are removed and humans regain consciousness, the memories are mixed and confused. How does this affect them? How do they benefit from it?
3. Do Melanie's memories of Jared match up with how he behaves in person? Why or why not?
