Comment by Fubukispersonalchair on Sousou no Frieren - Chapter 144

The beheading gives major Ubel vibes. I wonder if that's foreshadowing. It would make sense considering Ubel's personality. If this is the case, then the question would be why? If Ubel really is the one who's going to kill Serie, what would she stand to gain? I don't it would be her sisters location, since she already asked Serie for a spell that would help her locate her sister. The way I could see it go down is one of the shadow warriors copies Ubel's magic. Maybe the shadow warriors trick Ubel into accidently killing Serie. Or they offer her something for her to do it. Perhaps when she tracked down her sister, she found her dead or something. And the shadow warriors have some sort of spell that could bring her back. Or maybe they have her sister hostage. Or maybe Ubel has nothing to do with it and I'm overthinking
