Simon had been having a really...really rough week. While on a mission he had been shot in the shoulder and forced to take some time off to heal and get full range of motion back, which meant he had to take some planes back to England from the base they were on in America. Which meant he had to deal with people which meant he was grumpy.
All of that he could have handled were it not for the cancelation of his flight and forcing him to have to take two more flights to get home. He was incredibly irritable at this point and decided to upgrade himself to first class. It was so he could stretch out, deal with no one and have a seat next to nobody. He finally managed to settle in when he heard the flight attendants talking about how another flight had been cancelled so they were getting more passengers on the plane. He sat there, trying to look as intimidating as possible and for the most part it worked. No one wanted to sit with him. But as the airplane began to fill he saw one last person step on and with it being the last seat and all...
Simon sighed heavily, his irritation mounting as he looked away when you sat in the seat next to him. He just prayed that you weren't chatty.
