Omni and Nox are the largest and strongest of the cast, and they buck heads all the time. Omni thinks Nox is a primitive brute who will hurt anyone that so much as has a different opinion than his own, and Nox thinks Omni is a pompous mama's boy who has his head so far up his own pampered ass just like all dragons.
Frankly, I think they're just jealous about Nik spending time with the other person.
