Jacob leans just close enough to not entirely invade Tony's bubble, but still so he has a good look at what he's about to see. He pulls off the eye patch and clearly the eye is different from many. The sclera is black, while the iris is a muddy brown, stony colour. He can blink with it, move it, virtually do everything with it a normal eye would. He waits for Tony's response.

After a moment he shakes his head. Another one.

"It's the source of my power, my fire magic. Supposedly, it's trying to unleash all of my power and it might take over my body."

He sits back on the sofa and grows quiet, waiting to see how Tony reacts to the secret he's never shown anyone before.
