"Just hold him still, unless you know how to give an injection." Ronin snapped, setting the syringe down on a tray devoid of anything else on the cart nearby, and pulling on some latex gloves. "I'm not too drunk to treat an addict. I'm guessing he has 'uppers' in his system, which is pushing his heart rate through the roof. Once this sedative takes effect, it'll calm him down enough for the stuff to run out of his system. Not an ideal setup - if I were in a better place, I'd filter his blood. And maybe a touch on the dangerous side, but if he's this high and his heart rate keeps climbing, any method is going to be dangerous." Even though he was drunk, Ronin spoke with a surety that defied his appearance. He did, apparently, know exactly what he was doing. "If we don't slow his heart rate, he has a good chance of going into cardiac arrest, and I have neither the drugs, nor the equipment, to bring him back from something like that. So either you hold him still and let me inject him, do it yourself, or go outside and grab a shovel to start digging his grave."
Not really giving Jadyr a chance to argue either way, he picked up the syringe, checked it for air bubbles, tapping it to make sure there really were none, and leaned down to grab Jonah's arm - the latter so rabbit-sees-wolf scared that he made no attempt to get away, to move, or to even breathe too hard.
"Look, kid. Relax. I'm good with a needle. This isn't going to hurt as much as you think it is. If you relax, I can find a vein easier, and.... Ah hell. What am I saying? You're too high to care at the moment. Sorry, kid."
He ran his finger down Jonah's arm, and found a nice plump vein, pressing on it to make sure it wasn't going to roll away from him. This stuff had to be injected into the bloodstream, or else it wasn't going to do any good. Thus, he had to get the stick the first time. Which he did, surprisingly. It didn't take long. Ronin would have preferred to give the kid an IV, but they didn't have any extra tubing, and most of the bags were in freezer-storage, and would take too long to thaw out. This was a painful way to inject, and Ronin mentally apologized for it, even as the medication started to work.
Jonah went from feeling pain, fear, and anxiety... to pretty much feeling nothing at all. Then it all went away, as he slumped in Jadyr's arms, head resting on his shoulder, relaxing by degrees. The boy was out, and out good.
