A. “Skull guy” doesn’t exactly look like a female individual with a thin body(which is how Seo has been described in the past). Also not very in-character, if they are behind the signal. Which, at this point, is very possible.Seo Jin-ae?
The First Apostle of the True Chapters?
Salv-AI-tion?
B. Possible… but somewhat unlikely. Is more likely to be on the Testament in the middle of nowhere(Frontier’s lore pocket) right now.
C. Uhh… I guess? There’s certainly no points to make for or against here.
(Still holding open option D of ‘totally normal human that has not been messed with by Thargoids’.)
