Kendra: Charlie, I am not a neurologist. I don't know how coma's work, but I do know how the human mind works. This is your mind's home turf. If it doesn't want you to wake up, then you need to fight it, and you need to figure out why. And once you get the answer to that question, you're going to be one giant step closer to going home.
Charlie: How do I do that?
Kendra: You gotta...open up! Be brave. Look at the parts of you that you've hidden in order to protect yourself.
