Undercurrents

The sound of the doors of the emergency room broke the silence that was slowly freezing like a layer of thin ice. 

Everyone turned to look at the nurse who had stepped out of the emergency room. She looked awkward and scared as she glanced at the trash can that had been kicked down by Nicolai. 

"Umm. We are in urgent need of blood. As there isn't enough for the blood transfusion in the hospital blood storage for the time being if anyone is—'

"I will do it," before the nurse could even relay which type of blood they needed to draw, Emil stepped forward and raised his hand. "You can draw my blood for the blood transfusion." 

Nicolai narrowed his eyes as he studied Emil and asked suspiciously, "Do you even know which blood group they want?" 

"I know. It's O positive right?" Before either Keon or Mateo could stop him, Emil blurted out, and if anything that only intensified Nicolai's suspicions. Why did this man know something that even Ari didn't?
