Not Fit To Be A Parent
If Maria is not that afraid of her Father in Law's presence, Victor on the other hand is not sharing that sentiment. Victor knows his father to the very core. He might be kind and strict depending on the situation, but doing something that would upset him would make even the most notorious criminals and monsters kneel in fear. That is how dangerous Rakkan is even to his family especially when one disrupts the public and causes disturbance that would result in public chaos, fear, injuries, and even death.
And considering that they have done what is essentially called terrorism, his Father is bound to be sure that he will not take this event lightly.
"Victor, what are you doing? Why are you frozen in fear there? Don't tell me you are still afraid of your father even at your age!?" Maria found it incredulous for Victor to still fear Rakkan.
