So my sister had wanted a scenario where Bucky damages his arm enough that he loses it. Preferably saving Steve in the process.

So imagine him using the arm and its strength to wedge itself and stop something from falling on and crushing them. Whatever about his own self-awareness, Steve is out cold and he has to save him.

There was more in the private stream but I didn’t think to grab it.

And the second is the aftermath – Tony is working on his new arm while both are recovering.

I figure Bucky was facing the other way and sufficiently far enough away that Steve kicked his feet up

Then Bucky rolled in his sleep curling around, Steve probably woke when he moved and sleepily watched for a moment before drifting off again.
