Dean came inside the meeting room after Nina when he saw her in a rage. He wanted to save Marissa from her wrath but the scene before him had made him rooted to the spot.
He was horrified when saw Nina raising her palm to hit across Marissa's face, but before that Marissa's hand shot up with lightning speed, catching Nina's wrist mid-air.
There were gasps in the room when Marissa twisted her arm and a few of them even got to their feet in shock.
Dean quickly moved forward to pull Nina away from Marissa. Marissa was still holding her arm, with a deadly calm face.
"M…Marissa," Dean called her name, but Marissa didn't even acknowledge his presence. Instead, she spoke to Nina in a low voice that was surprisingly controlled, "I wouldn't do that if I were you, Mrs. Sinclair."
Nina was struggling to free her arm. Her face had turned dangerously red, and Dean didn't know if it was due to pain or her anger, or the humiliation she just faced.
