Concussion

Three followed the potential target's orders as she conducted the examination. She clucked at him when she was done. 

"Definitely a concussion. You must have hit your head when you fainted. The guy that called 911 for you saw you go down. Were you not feeling well? What happened before you passed out?"

"I was hit with several tranquilizers and did not give myself adequate time to recover before moving around," he replied. 

Her eyes widened. "Tranquilizers! How did that happen?!"

Three realized belatedly that he should not have told her that. Targets didn't know anything about his world. He needed to get out of here as quickly as possible before he gave away too much about the Agency. She might report him to the police then he wouldn't be able to meet up with the other agents that may have gotten out as well. 

"During a fight," he said simply. "What do I need to do about my concussion?"
