The angel that came to Inteus is not easy on him one bit! When these types of angels close their third eye it's a sign that death is coming. The fact it's angry on this specific meeting is because the gods are mad at Inteus for the bad things he has done. He's getting a warning that he is going to be severely punished if he doesn't stop doing what he is doing to anger them...!

He probably won't change though haha tsk tsk tsk! Shame on you Inteus.
