Dust filled the room, making him cough until his eyes watered. Talking or, really, even breathing easily was out of the question. Between the dust and the heavy weight on his chest, he was effectively breathless.

Hold up. That weight on his chest had a name. He managed to cough out enough of the dust and smoke to choke out, "Bucky?"

There was no response except for the scrambling of what few Hydra agents remained. They had to be taken down, and fast, and Tony really was in no condition to fight. He had no suit, no weapon unless he made the mad dash to the pantry, and no particular skill with a handgun.

Then again, he also apparently had a man down (down meaning right on top of him), and he wasn't exactly going to let that go. He rolled Bucky off him and, eyes tearing up from the dust in the air, scrambling for whatever weapon lay closest to hand. As it turned out, the gun in Bucky's belt had managed to survive the blast (don't look at the blood on his face, just take the gun) and he aimed with shaking hands at the first shadow to move in the dust, then the next.

A few times, bullets flew past and embedded themselves in the kitchen cupboards, but Tony was crouched behind what was left of the dishwasher and hard to see, much less hit, in all the chaos. Something was on fire, and Jarvis was delaying the sprinkler systems because he knew the smoke was playing to Tony's advantage. I love this AI. Bucky was pretty safe, his body (don't say body) tucked between the remains of the dishwasher and a mostly intact section of counter. That area wasn't on fire yet, and the enemy didn't have a line of sight. It was as close to safe as there was in a situation as dire as the one they were in.

Tony, on the other hand, wasn't anywhere near out of the line of fire. He had the best cover he could find, but since he needed a line of sight to anyone approaching… well, it worked both ways. Jarvis tried to give him directions to any heat signatures he detected, but there was only so much the AI could do with so many of his connections to the floor severed either by Hydra or by the explosion. "J, make a note," he muttered. "Find out who the hell made their grenades, and either burn down their factories or buy like five hundred for Clint." One of the Hydra agents apparently emptied a whole clip in the direction of his voice (he had thought he was being quiet), and one bullet grazed his left arm. He bit back a hiss of pain and fired back.

"Two degrees to the left, sir," Jarvis informed him, and he adjusted his aim before his opponent could move. A cry informed him that his shot had been accurate. He loved this AI. "I believe that was the last one, sir." He really loved this AI.

"Sure hope so," he said between coughs. The sprinklers finally came on, and he crawled the few feet between him and Bucky. He didn't think he was injured too badly, but it was better to stay low in the smoke, and his ankle felt like it was on fire (he had checked: it wasn't actually on fire, so at least there was that). Bucky was definitely out cold, which probably had something to do with the fact that his back was chewed up with pieces of metal and marble. "Shit! Jarvis, call - oh. Right. Wanted fugitive. Uh, Jarvis, are there any doctors in this entire building?"

The AI sounded honestly concerned. "Sir, there are no licensed medical professionals in Stark Tower. The hospital is only three blocks-"

"No hospitals," he responded immediately. If he walked into a hospital with the Winter Soldier, or called an ambulance or any sort of emergency service whatsoever, it was the same as condemning Bucky to the death penalty. On the other hand, if he did nothing, well, it wasn't going to be pretty. Which left exactly one option, and he didn't exactly like it. "Right. Jarvis, you're going to have to get me as much information about what to do for this kind of wounds as you can."

"Sir, Sergeant Barnes will require at least seventeen stitches, I think it would be best to call an actually doc-"

"Seventeen stitches? Right, okay, got it. I should probably try to clean the wounds out first, though, right? Fuck, which cabinet are the dishtowels in?" He interrupted the suggestion to call a doctor immediately. Now that he had evaluated his options, he was going to stick to the decision he had made. "Jarvis, you're going to help me with this, right?"

The quiet reassurance, "Of course, sir," was as welcome as it was expected. This was absolutely a bad idea, but it was the best of the bad ideas, because any other choice meant death for Bucky. "You'll need to boil water."

"Well, it's a good thing I'm in a partially destroyed kitchen, isn't it?" he muttered, and got to work.

In which, if you notice, Tony has completely stopped calling Bucky by his last name...
