No one quite knows who or what they are. The memories you have and the role you were assigned are burdens you have to carry. It doesn't matter if they were real or not. That's never the point. There's no such thing in the world as absolute reality... We can tell other people about—having faith. What we had faith in. What we found important enough to fight for. It's not whether you were right or wrong, but how much faith you were willing to have, that decides the future.
