Tanaga was almost to his office when he remembers Ashley. He stopped for a moment long enough to see if she's coming. When he saw that she was almost near, he turned around and continued walking towards his office without waiting for Ashley. He was acting as if he was alone and went straight to his office without saying a word to his assistant.
Meanwhile, Ashley was in deep thought as she saunters back to Tanaga's office. When she arrived at his door, she was hesitant if she was going to go in or not. Since he didn't say anything and just left her on her device, she decided not to follow him and went the opposite direction.
The truth of the matter was, she was pretty upset, and from the way she's feeling at the moment, Davinchi won't even be able to paint her face. She couldn't believe how he sternly told everyone inside the President's office that she's only a mere assistant and no need to be introduced to the higher up.
