Nope still not buying it. They froze her corpse, so it will be perfecty fine until healer girl figures out how to call back souls. I've seen this shit before author, you an't slick.
It feels like the author is trying to make us believe that Selka is dead for real because the previous chapters were only talking about Selka's death. Of course she won't stay dead. It's a world filled with magic and shit. Resurrection should be thing.
