In my experience, fire is harder to spot early on besides blushing, the color is pretty subtle and then over time it brightens up a lot. I don't really see any blushing in the darker areas drastic enough on non-spiders to think it's that. Enchi is a lot more likely. From what I can see of the sides of the heads, some of them do have the tell tale enchi face stripe, but I would feel more confident if I saw particular ones from the side of the face. The second pic of the sire, he seems to have extremely thin dark stripe under the eye like an enchi would have. The past two sets, are you able to get a side by side comparison of that part?

See on this pic how the lighter stripes even seem to connect over the eye? https://www.morphmarket.com/us/c/rep...pythons/584163

It's less drastic in non-spider enchi, but it still thickens the lighter stripe over the eye compared to a non-enchi.
