Headcannon: Rahzun's kiss has the tendency to take people's strength making them weak and sick making it easy for Rahzun to take their souls and can also do this while possessing Americus
He also tried to do it on Collin Rayne and Monica but failed to do so but tries it again on Rayne while trapping her and when he finds her interesting while possessing Americus
Once Rahzun gets a new vessel he'll probably kiss them
