"Crap! They are here! I have to buy more time. System show me all the surveillance cameras, and create a map of the people inside the building." 

He saw several men entering the facilities with lab coats and equipment. Some were carrying guns and were tossing the employees into the main auditorium. Meanwhile, a man in a black suit and other with glasses were arriving at the head's office.

"Tha... that"s him. What is he doing here? He doesn't know, right?" Then his eyes focused on the entrance to the main lab where the young and her parents were standing. "Wait! Why don't they come in? What are they waiting for?" he narrowed his eyes looking at them, especially the young woman. Then a message came to his phone and a smile appeared in his face.

"Great!, that gives us some time... System alert me every time someone approaches the doors of the inner lab."

Looking around the building's cameras, he fixed his eyes in one particular location.
