In the very least, I think we can agree that the Sub Ceadeus does go blind, but is still a deadly force. It is not like it doesn't know where the hunter is when in a fight. I like what Lord Loss said about the age being a factor. It’s possible that Sub Cea is just an old Cea that has focused on some other way of detection, like sonar or something similar, in exchange for more power. Maybe the eye is only there at the start of its life till the horns are in full length. Within that time, the new way of detection could be still developing in the dragons’ body. This is all purely speculation, of course.

As far as Jhen Sub, I think I remember the Guild Elder in Tri talking about Jhen in twos, like a yin yang. One for prosperity and one for war. Is it possible that normal Jhen is prosperity and Sub represent war? It certainly is more hostel than normal Jhen and it would help the canon reason that it just now coming into the picture, right?
