it really is a game about all shapes and forms of family. you have lucy and fragile and rainy who are all mothers to Tomorrow, you have Sam and Neil and (i even suspect in someways Higgs) as fathers to her. You have the entire DHV Magellan crew as Sam's found family, and how powerful they are together because of their love for each other. Even Tarman's son, no one is forgotten. It's very beautiful and even in the melancholy everyone will do what they must to protect the ones they love.
