In my story, the job of one of the MCs (Jack) is to find people on this list and bring them to safety before they are killed (too long to explain). He used to have a brother (Ben) who was his partner in finding people. Ben is never really in the story but Jack explains to the MC (Hailey) that he was killed while the two of them were out looking for her. Now, I haven't really figured out how exactly he dies. I want it to be like he had to do this to save his brother. Like, perhaps the two brothers were being pursued by the people trying to find and kill Hailey and Ben sacrificed himself somehow so Jack could get away. I'm having such a hard time though coming up with an amazing, heroic death. The reader never actually meets Ben, but I still want them to love him and I want his life (though short lived) to be memorable and his death to be tragic. Does anyone have any sort of idea that could work? Or perhaps examples in books you've read or movies you've seen that I could use as inspiration?
