The chains pulled him away, retracting into the wall until he was held flush against it. The Chitauri chattered as they approached.

What to do with the other?

Kill him, he is of no use

"No!" Loki had no idea if this would actually help, but he had to try. The only way he was getting out of this was if Bruce stayed alive. "He was the green beast who beset your army. He could be useful."

Silence, oath-breaker.

It began with quiet grunts and gasps of pain. They were a mainly auditory species, and Loki was not about to give them the satisfaction of hearing him scream. He held out as long as he could; it felt like an eternity, like he was falling through space all over again but this time instead of a cool numbing, it was accompanied with fiery pain. White hot energy coursed through him with ever blow of whatever strange device they were using to strike him.

Finally it happened: he screamed. It was a hollow sound that ripped through the darkness and reverberated against the cold stone walls. He screamed more, louder each time, until his throat was raw.

What seemed like hours later they left as they came. The chains loosened and he fell to the ground , a crumpled bloody mess. Again.
