Hello Sergeant (Bucky Barnes)

Insertion

Sarah's POV

I watched James' eyes close, giving him a moment to go completely under before rolling him over onto his stomach and pulling off his sweatpants so Tony and Bruce could put the trackers in. Tony gave me a look, but I ignored him; I wasn't straining myself.

I opened the access slot on James' arm and connected him to my computer to update his cybernetic arm and add in an updated tracking software that would activate a beacon if he was connected into Hydra's computer network. I'd hacked enough of their systems to know they wouldn't be able to detect my beacon. The only thing I couldn't anticipate was if they replaced his arm.

"Jarvis, block audio and stop recording on all lab cameras until James is awake again. No information on the physical location of James' trackers is to be revealed to James or anyone else outside of this room – you are to deny any and all knowledge of these proceedings."

"Also, don't update James Barnes' medical records," Bruce added.

I do not understand.

"Jarvis, you understand how James' activation words work, right?"

In theory, yes. It's very Jekyll and Hyde.

"It's more like me and the other guy," Bruce said. "If his trigger sequence is used, he becomes the Winter Soldier again and he can be made to tell Hydra the location of his trackers. If they capture James and remove them, we won't be able to find him."

"Bruce, will these show up on his scans?" I asked.

"Maybe an x-ray," Bruce said absently, making a small incision on James's butt cheek – one of the few places he wouldn't be likely to notice a tracker in. "Isn't there any place on his body that isn't scarred in some way?"

"Not really - he doesn't remember where a lot of them came from yet, so please don't mention it to him; he's ashamed of them - even though we've told him scars don't change how we feel about him."

I looked up at Bruce, who nodded. Out of the corner of my eye I saw Tony rubbing his hand over his chest where his arc-reactor was located, making a mental note to talk to him about it soon. James wasn't the only one who was a little self-conscious about his scars.

"Where are you going to put the other one?" I asked Bruce, going back to typing on the computer and finishing my command sequence.

"Under his shoulder blade, where it's less likely to be noticed. He already has a scar there that will hide my incision."

"Will these trackers show up on an x-ray, Papi?"

"Nope. They're made mostly of the kind of plastic that doesn't show up on anything other than a really good ultrasound. I'm not sure how fast his body will break them down, but Jarvis will tell me when he's no longer receiving signal from them. I based them off the receptors I developed for Mark 42."

I looked over at him to see his face. "You've tested them since then, right? Pepper told me they don't always work the greatest."

"Yes, kitten, I've tested them." I could almost hear his eyes rolling at my question. "Have you decided where you want your trackers?"

"Forearm and butt cheek. Forearm will be the easiest to replace when it fritzes – I give it two months before they need to be replaced."

"Guess we'll find out," Tony said with a twitch of his lips, his gaze moving past me.

"I'm almost done, Bruce. How about you?" I asked, glancing over at the scientist.

"He really does heal as fast as Steve. I almost can't tell where my first incision was anymore."
