A/N: Again, apologies for the wait. For this passage I'm assuming that they all probably know sign language. Nat and Clint for work, Bruce because of his travels, Thor because of all-speak, and Steve is just the kind of guy to learn it so he can help people. It's not just for plot reasons, I did think it over and consider whether or not they would all understand.
On the medical side of Tony's voice, the way the voice box was cut out makes it impossible to do a transplant-the only viable method of letting him speak again. As far as my research found out, only 2 successful larynx transplants have been performed ever- The first in 1998, the second in 2010 to 52 year old Brenda Jensen at UC Davis. This type of highly experimental procedure would not even be considered with the amount of damage Tony has.
Storytime
*Four years ago I was kidnapped leaving a weapons demonstration. The Ten Rings wanted weapons and didn't care what happened to me as long as they got them.*
Tony shifted, uncomfortably aware of everyone's gaze and the probable bugs. Everyone else seemed fully prepared to ignore the fact they were likely being watched in favor of information, but Tony hated it. He didn't want some weirdo knowing this. However, he knew the others were to out of focus to plan an escape now, not until they knew. This is why he didn't like being fussed over.
Tony took a breathe then resumed signing. *They wanted me to build the missile I had demonstrated. I said no. They tried to convince me. They had a few methods."
At this Tony paused, focusing on Bruce. He didn't want a Hulk out, there wasn't enough room for that.
*Their favorite was waterboarding. They would force my head into a bucket of cold water until I inhaled it. But they couldn't do it much. I didn't have the arc then. The open circuits would electrocute me because he connection between the Car battery and me-*
Tony paused as everyone lost their composure and began to curse. They had a few rather creative threats. Once everyone refocused on Tony he started again.
*The connection between me and the car battery was unsafe, with some exposed wires. They didn't want me dying, so they had to stop after a while. The constant electrocutions and the water in my lungs would have killed me. So they moved onto other methods. When this,* Tony tapped his throat. *Happened they were using knives. I was threatened that if a made a sound other than yes they would cut out my vocal cords. I screamed. They followed through. By the time I got back to the states it was far too late to do anything for me."
Tony paused again. Bruce, his science buddy and brother in all but blood, looked furious. He had his teeth clenched and if it wasn't for the drugs he would have lost it.
For that matter, everyone looked angry. Bruce and Nat were the worst though. This was unsurprising, as they had both taken the roles of older siblings to Tony.
Tony moved to sign again, but Natasha spoke.
" You don't have to say anything else Antosha. It can wait until we are out. We need an escape plan"
