Germa Cover story will reveal that the vinsmokes actually have emotion & still being strong.
Also Pedro and Pekoms being fine ofc.
I've suspected the Vinsmokes have emotions, they just lack empathy which would make them the ideal super soldiers. Judge also removed fear from them too, I'm guessing any forms of sadness, anxiety/despair, desire and such too.
But they've shown to lust over women ofc and they I think they showed a bit of apprehension/fear around the time they were gonna die to the BM pirates at the tea party?
I can't remember specifically of what I'm thinking of but I felt there were very subtle signs they weren't entirely emotionless either. Didn't Sora's drugs affect them all too but only truly worked on Sanji or on him the most by far?
I do see their ultimate character arc being them being freed from their super soldier slave existence somehow, I thought it would happen as an end result of WCI due to Sanji somehow, maybe something to do with his cooking too or maybe it may happen later on with Vegapunk helping instead? This cover story might lead up to that somehow?
