So what legacies do your characters leave for your readers? Are your characters leaving the kind of impression you meant them to leave? If not, why not? Do your characters surprise you and if so how do they do so? I must admit I love it when my characters show more depth than I originally planned. It is the sure fire way of knowing your characters have real potential and the way you've written them is not going to get in the way of that being shown.
What emotional legacies do your characters have? Have they inherited a stiff upper lip attitude or are they keen to wear their heart on their sleeve? Is this affected by the differences in the generations? My generation finds it easier to express emotions in ways that my parents' generation did not. So legacies can be something that you're expected to attain to as well as what you already bring with and/or automatically inherit.
