Disclaimer: I don't own MASH. I simply borrowed some of its characters for the simple purpose of fun.
Author's note: English's not my mother-tongue, so may my mistakes be forgiven.
It's kind of AU. I introduced certain characters and others play a smaller role than they did in the show. I tried to follow the timeline of the series though.
It was a boring week for the people of the 4077th. With no new casualties arriving and just a kid with a hot appendix in the post-op ward, the crew (especially the doctors) had too much free time on their hands. And boredom was one thing they couldn't deal with. There were no more pranks to play, no more movies to watch, no more new nurses to seduce and no more good booze to drink. To survive this depressing week, Colonel Henry Blake, the commander of this MASH unit, had ordered a doctor from Tokyo-Hospital who should demonstrate some new techniques. Although everyone could think of better ways of distraction, they were happy about every diversion that came along.
One fateful morning, Trapper John McIntyre and Hawkeye Benjamin Franklin Pierce took a stroll through camp after they had some of the worst martinis ever from their still for breakfast. It was far too hot to eat. Not that they missed powdered eggs and watery coffee, but they hated the heat even more. They were having a really bad time and were talking about a way to survive the day without dehydrating, when a jeep passed by them and came to a halt a few feet away.
On the backseat of the jeep the pair could only make out slender legs in khaki-shorts that rested upon the front seat. Suddenly the owner of these legs jumped out of the jeep. She did this with such élan and grace that it surprised Hawkeye. He wasn't used to this kind of spirit anymore. Not in this place at such a time. She thanked the driver, gave him a smile and took her bag out of the jeep. As soon as the driver took off, she took a good look around. She noticed two guys watching her and made her way towards them.
"Hi there," she said as she let her bag drop to the floor, "I'm looking for Colonel Blake's office." "Hi yourself," Trapper said, "We're going to show you. It's probably the most useful we will be doing all week." The sound of this voice seemed familiar to the new girl and she took a closer look at its owner. "What the…," she shouted all of a sudden, "John McIntyre." And before he knew what was happening she gave him a big hug that nearly crushed his lungs. Trapper wouldn't be Trapper if he let the opportunity of having a beautiful girl in his arms pass, so he hugged her back. "I can do what I want, they can't keep their hands off me," he joked in Hawkeyes direction. Hawkeye smiled and waited patiently for the hug to end and for Trapper to introduce him. But when they pulled away again, the confusion in Trappers face was evident. "You don't remember me, do you?" she asked, and Trapper smiled apologetically. "Well, you know how to flatter a girl," she said with good humour. Hawkeye, never afraid of a corny line, whispered "I'm sure we haven't met before; or else I certainly would remember." The girl just smirked.
