This is about Charles showing his worth. I hope I've done him some justice. The italic stuff is a voice in Charles' head. Spoilers for the life you save. Tim is his brother.
NOT Frank Burns
Charles Emerson Winchester the Third sat at the bar of the Officer's Club in Seoul, nursing his final cognac before departing back to his humble cesspool known as the 4077th M*A*S*H in Uijongbu. He had received a three day pass from his CO, Colonel Sherman Potter after returning from his mission on finding out about death at Battalion Aide a few nights ago.
Potter thinks you've gone mad.
"Rest In Peace, Tim," the Major sighed into his glass before draining the contents and setting it down on the bar.
The door of the OC opened and a lanky young Corporal who could've been no more than eighteen stepped through it and was about to call for Charles when a drunken one star General burst boorishly in behind him.
"Outta my way, pee wee!" hiccoughed the tank-like figure to the stunned Corporal who by now was shrinking like a violet.
"I'm, s- s- sorry, General," answered the boy, his voice quaking along with his body.
Before the General had time to answer Charles stepped over towards the boy in an attempt to guide him away from his assaulter.
"Let us be on our way, Corporal" ushered Charles turning towards the door.
"Wait, porky. Let the boy fight his battles." slurred the General grabbing him by the shoulder so he could see who had disrupted his fun.
Oh god. It's him.
"Huh. Well I'll be damned, Chuck Winchester the Third!" scoffed the aggressor heartily.
"Ha, Colonel.. General, rather Penobscott. How the devil are you?" Charles smiled in return while inside his head he felt his brain melting already.
"Great, thanks. I think you can help me."
"Oh?"
"Yeah. Look, I'm going back to 4077th, ok?"
"Mmm hmm"
This is going to end badly.
"And if you could help me.."
"Yes?"
Wait for it, Major.
"Get Margaret back."
Do it Charles!
Charles didn't know how he mustered the strength and he didn't care why all he knew was he won't stand idly by as this brute would try and hurt his dear friend.
He stood over Penobscott his fist still clenched, blood dripping down his knuckles and the fallen monster's nose.
"If YOU step own toe inside the 4077th I will not be held responsible for my actions. You've hurt Margaret enough. Now if you don't mind, General I will be on my way," Hate was spat out with every word he uttered.
The corporal followed him outside towards the jeep like a lamb. As they sped off to Uijongbu Charles ignored his bleeding hand allowing the blood to dry as a reminder than he could be altruistic sometimes.
Next chapter Potter puts him in charge while he goes to Battalion Aide and for once he underestimates Chales.
