Crowning Moment of Heartwarming: In Firewing, this conversation between between Shade and his son, Griffin, just before Griffin returns to the World of the Living, making these the (almost) last words they speak to each other. Qualifies as a Tear Jerker and So Proud of You as well.
Griffin: But I wasn't brave! I'm not like you. I'm a coward.
Griffin: I was always scared. Always.
Shade: That's right. Being scared but doing it anyway. That's brave.
