I also hope they revive Selka. Her death was kind of pointless (insta-death because she hit a guy in the heart but happened to be an immortal zombie that only the most OP guy in the planet could fully kill, while no one else did a thing until it was too late and her aunt that was supposed to protect them nowhere to be seen) and it makes all other conflicts introduced also pointless (her mother being a traitor of humanity, the conflict between her and the aunt over the inheritance the fact that her weakness was solely caused by her aunt's lack of faith in her). The lesson with her dead isn't even a particularly good one, just that people die if they are unlucky and things conspire against them, even if they had put the effort in their training and did things technically correct in an effort to save people.
