Azzen's entire demeanor changes completely upon seeing the advancing King John. It was not the power behind the golden aura that froze him like this, but it was the scent coming from the golden aura instead.
Not one Supernaturals can forget the scent of their suppressor for thousands of years.
Despite they were sealed away by the ancient humans for thousands of years, the particular scent that they emitted is engraved inside their minds and wouldn't be able to be forgotten even if they wanted to.
The impact of the ancient humans is that strong in these Supernaturals.
"H-How come you have their scent...? No, this is impossible, there shouldn't be two of you", Azzen mutter with a stutter, he even unconsciously takes a couple of stiff steps back, backing away from the advancing King John that doesn't seem to be surprised by Azzen's reaction.
Slowly King John's eyes turn completely golden and so does his hair which is dyed the same color.
