I haven't read the novel

This is what I found on media "@revi. :don’t read this comment if you don’t want spoilers, but based on how i understand the novel, his eyes turned grey because his ghost alpha nature is beginning to surface after the knotting. with that being said, knotting is the moment when beta starts their shift to an omega, and to my understanding, this panel itself signifies that the transformation has begun :)"
