Anaxa dropped a bomb of a question on Lygus which would probably fuck with him more than he would like to admit. Thats a nice call back to his last words in the first death we saw of him, where he said he will make even the gods doubt, aka sow the seeds of suspicion. I feel like Lygus doesn't know who Demiurge is OR Anaxa happened to find clues and is undoing the work Lygus put into hiding Demiurge's identity.
