Sherlock didn't often get ill but it was clear to see when he did he got it bad. He had never seen Sherlock in such a vulnerable state before. He tried to look away, he didn't mean to stare but he couldn't help it, he just stood there and stared at this fragile broken man. Naturally, as his doctor, John felt obliged to help.
"Come on" John grunted as he tried to lift Sherlock out of his sunken position on the sofa. "What is it this time?"
"This time? John, as my doctor how often do you see me in such a state?" Sherlock spitted.
"As your friend plenty of times, after every case in fact" John retorted. Sherlock collapsed back onto the sofa and let out a great groan as he sunk his face into the tatty cushion.
Sherlock was displaying all the signs of case withdrawal, John thought. Excessively bad attitude, hasn't slept, same dressing gown for four days, same pyjamas for three days. And no doubt patches.
"Roll up your sleeve" John demanded.
"Why should I?"
"You know exactly why! now roll up your sleeves of I will come over there and do it myself"
Sherlock forced himself up from the cushions that surrounded him and pulled up his left sleeve.
"FOUR?!" John shouted in horror "...four" he said with almost no emotion. "Why could you poss-"
"Four patch problem" Sherlock interupted in his usual dry tone.
"What could possibly require four patches? You my friend have a serious problem."
"No problem, John. Lots of nicotine thus problem has gone"
John walked towards his room huffing "I give up, I really do."
"You're dissapointed" Sherlock stated. When it came to these things Sherlock never asked, he knew.
"What do you expect Sherlock? You were doing so, so well and now just because you're bored y-"
"I am always bored John, comes with seeing everything and nothing changing. Now are you going to stand there mothering me, or are you actually going to assist in my getting to my bedroom?" Sherlock hissed with a quickening pace. John smiled smugly, and Sherlock knew exactly what that meant.
"I have influenza John, have done for a few days I've just been ignoring it. My sinus' are slowly closing in, my brain is becoming dehydrated and the blood flow restricted, and now my limbs are ceasing to function as I command them, so yes. Doctor John Watson, I require your assistance to get to bed."
