Clint felt relieved when Tony woke up and grateful when he sat up, as it meant that Tony probably didn't have any major injuries. He knew this just meant their captors would hurt him too but at least Tony wasn't dead from whatever they had drugged him with. He answered Tony's questions quietly, focused on scanning him for any wounds he might have missed.
"I'm going to get us out of here, Clint"
Wait. What?
"Tony! What are you doing?" he exclaimed, alarm bells blaring through his head. Tony slumped forward as he whispered something, just as the guards entered the room. He immediately blanked his face, hoping against all hope that Tony knew what he was doing.
He stared in complete and utter stupefaction as Tony straightened up, gracefully sliding to his feet, the ropes somehow slithering off his body. He was sure his blank mask had shattered into one of incredulity and his jaw had dropped, leaving him gaping like a fish. Then Tony, no, whatever it was it wasn't human, turned to stare at him with completely white eyes, through Tony's eyes.
The being waved a hand with grace that Tony had never had, and the guards, who had been frozen in shock, dropped like puppets with their strings cut. A snap of the fingers had all the locks opening and the four cell doors creaking open. The manacles around his wrists and ankles fell off, and he took the chance to stand up, wincing as pain shot through his bruised ribs.
"Who are you?" he demanded nervously, "And what did you do to Tony!"
The being turned to regard him, the completely white eyes unnerving him more than a little.
"I am Death, the End of All Things."
Wait. What?
