When they were allowed to see him, Lestrade politely declined, saying he had to go, which John knew was partly true. Kidnapping cases always involved a lot of paperwork, and ones that involved both the Holmes brother could only be hell as far as that was concerned, but John knew it was more than that. He knew that half of the Yard believed he was in a relationship with Sherlock, and the other half probably believed they hadn't yet made a move, and Lestrade was no exception. He wanted to leave John alone to greet Sherlock and do whatever else he may.
So while John was irked by the implication, it certainly was nothing new, and appreciated the privacy he would have with Sherlock, so he could yell at him or admit how terrified he'd been, without an audience.
It was probably best that Lestrade wasn't there, as John nearly burst into tears at the sight of Sherlock. Whether they were tears of relief, or whatever else, that was anyone's guess. It had been an emotionally fuelled couple of days, and John really had no emotional defences left.
He sat down at Sherlock's bedside and gripped his hand.
He was intubated, IV lines everywhere, various other tubes snaking out from under the covers, wires and patched dotting his chest, and the most alarming, double tubes leading to what John recognized as a dialysis machine.
Probably just a precaution, he assured himself, knowing that shock could lead to organ failure. Hopefully they had gotten to him in time, and this was just a little push until Sherlock's kidneys could handle the full load on their own again. And if John knew him at all, if Sherlock awoke and found his kidneys weren't working, he would talk them into working.
Hopefully it wouldn't come to that.
He had a feeding tube and central line, trying to replenish all the fluid and nutrients he'd lost, as well as fill him with antibiotics to fight the infection, and sedatives to allow him to sleep.
John could use some sleep, which was what he realized just before his neck gave up on holding up his head, and collapsed on the foot of Sherlock's bed.
It would do for sleeping, just for now anyway.
