Bucky nodded. There was no reason to stop her now. The scars didn't bother him, they were just a part of what had been done to him. Like the arm itself.

"It's more powerful, and tougher. Makes a good shield, bullets don't hurt it. I can lock it in position, too, helps for grabbing things. But my reflexes and most of my speed and power is from the serum. The arm is just a boost. I doubt they'd have bothered except for the fact that I was already missing mine."
