The operation was efficient in what it did, just go in, remove what was damaging, repair what was damaged, add to what couldn't be repaired, patch it up with some Droksin and Niskord, give it a day or two, then it's all apples. All of this done in about half an hour - then then Hicks was seeing to getting his jaw replaced.
Henry's body was carted over to his bunk, and he was left down in his quarters to recover. About half an hour passed, and Henry roused from his drug-induced sleep. He had bandages on his right leg, and a note left by his bunkside table. He put on his reading glasses.
"Henry. The operation was a success. I recommend you take it easy for a week or so to let the drugs do their thing. A crutch has been left with you for your courtesy."
Henry looked over and noticed the crutch, shrugged, then continued reading.
"We made a joke about your leg being an 'Arse Kicking Leg', since the replacement muscles were significantly stronger than what was there. Make of this what you will. Still, I don't want you to test this theory until you've rested. Regards, Doc."
He let the note fall out of his hands and laid down in his bed, leaning over to turn the bedside light on, and pulled out one of his favourite books and put it next to him. He then reached for his notepad and a pen, and begun drafting some rough sketches for a rifle of some sort.
He wanted the mechanism to be durable in bad conditions, manually powered and easy to clean. He figured out that a lever action would be suitable for this task.
Next he had to think of a bullet calibre, which would allow him to do the rest of the calculations. He figured out that a large-bore pistol, such as a .454 calibre around would suffice. This would also allow for a .45 to be loaded if it required - albeit with modification.
Either way, he begun making drafts and sketches of this weapon, occasionally burning through a cup of coffee with a dash of brandy to keep him busy.
