The part when Zoe's e hits Neeko, you can see all of Neeko's teammates fall into the eye. Probably I'm just over-analyzing it, but everyone's doll eyes were normal except Miss Fortune's. Her eyes were x'd out as if she died.

If you note Jared's twitter post about the new bio for Prestige SG Neeko here, they suffered a brutal loss of their lost companion (not plural so I'm assuming it's one companion). Everyone speculates it's Rakan as his bio and recall showcase him sacrificing himself for Xayah, but maybe it turns out to be Miss Fortune?

I don't know, but I just wanted to share and see what everyone thinks as well! I love theorizing the future of Star Guardians and hope y'all do too.
