Adrian tried his hardest to keep himself from fuming and baring his fangs in front of Grisham.
This is the second time they are meeting each other since his return. Now that he has his memories back, he can't help but fail to recognize him as someone related to him. He firmly refuses to accept this man as his grandfather - he is nothing but a cold-blooded demon in his eyes at this point.
Still, Adrian forces to keep it all in. He needs to pretend for a while longer - two can play in this game. Charles seems to be faring better than him as he only greets Grisham with enviable calmness before excusing himself and heading to his office.
"Good morning, Grandfather. I'm deeply sorry for not meeting you any sooner than this..." Adrian started and approached him, feigning amicability all the while.
"I should have taken better care of myself. That way, I would not fall sick. I could have caught up with you as well."
