Harrison shoved pass the father, the daughter and the other younger man they were talking to, to get through to a sink. He placed his hands at the side of the sink and looks in the mirror. He received a glimpse of his reflection and the reflection of the other bathroom occupants before vomiting into the sink. It was a simple puking. The only thing coming out of his mouth was his breakfast and possibly part of his lunch. Harrison looked at the vomit and checked quickly for any abnormalities that could cause worry for him or panic for the ones around him. The spew in front of him was ironically healthy: green-yellow with hints of food but no blood, small organs or any unusual colors. He reached for a towel and wiped his mouth with it. 

"Sorry you had to see that." Apologizes Harrison. They seem to be a little tense after seeing him vomit. "You can calm down, I'm not infected." He puts the towel back. "I just saw something that didn't exactly agree with my stomach." He then goes to the door and makes sure it is closed. If these two men and a girl can act calm when seeing some vomit in a quarantine zone then who knows what will happen if a panic-stricken stranger walks in and sees spew in the sink. For Harrison, it'll be a one way trip to see his brother.

"I have something to tell you both. I normally wouldn't say this to random strangers but you have a daughter..." He points to the father. "...and you are too young to die in this hellhole." He then points to the young-adult; looks 20, 21. 

"This airport is not safe and we need to get out of here. I sneaked into one of the staff toilets for a private pis-I mean pee." He hesitates at piss when he realized a little girl was in the room. "In there I found one of the soldiers infected and vomiting violently in one of the stalls. When I went to check if he was ok, he tried to attack me. It was like watching a rabid dog hound after a fresh piece of meat. I have never seen anything like it. I managed to kill it-I mean him-I mean...I don't know the proper pronoun! When it was dead, I got out of there and came here to vomit." They continue to stare at him, maybe worried.

"If one of the soldiers was infected then that means the terminal is breached. I know this because I have been in quarantine zones, I'm a..teacher of biology." He hesitated. He was going to say doctor but he can't. It is a path he chooses not to go down again. He looks at the little girl. He hates confronting strangers but if he lets a father and a little girl die today because he didn't have the balls to warn them, then he wouldn't be able to live with that. Harrison is a father too. He understands paternal care. 

"We need a way out of here." Harrison waits for a reply. They could help him to escape or report him for being 'mad'. He eagerly waits for a response.
