Feyd breathed as deeply as he could without hurting his ribs enough to break his calm. He focused on feeling his own body heat, on trying to increase it beginning with his heart, then pushing it up his chest, into his shoulders, down his arms and into his hands where he tried to focus it all together. He couldn't tell if he was sweating, or if he was still wet from almost being drowned. He was trying to be as conspicuous as possible about this, and he really hoped he didn't start to steam or something ridiculous like that.
He opened his eyes for the first time and focused on his hands. More specifically, he focused on the air between his hands. He wasn't even sure if him manifesting his own fire was possible, but he didn't think about that. He tried to push the heat from his hands to the area between them. He visualized a flame in the space. He imagined that he could feel the heat from the flame on his hands.
He focused on—holy shit, it was actually working! There was a brief flicker, not much bigger than the fire his Zippo would have produced, but he saw it. He focused again, visualizing throwing a huge fucking fireball right into tin man's face. There was the spark again, but it was stronger this time and Feyd thought it lasted a fraction of a second longer. It would be satisfying to torch tin man, but that wouldn't get him out of this cage.
It was a normal cell, with a lock and all. Feyd couldn't imagine that it would be too difficult to burn whatever locking mechanism was keeping the door in place. The bars could be made of special metal, and the lock even could as well, but Feyd doubted that the inner workings of the lock were impervious to heat. There were only so many materials that could be used in a lock, and Feyd knew from experience that precious few of them were fire proof. No matter how diabolical whatever group tin man worked for was, he doubted that they would burn through the time and cash to custom make a cage just for him.
The spark returned, except it didn't flash away. He heard tin man clicking away at the computer at his desk. Feyd tried to increase the heat, and was pleased to see the orange and red orb slowly brightening into an orb of pure white. He quickly snuffed it out so he didn't draw attention to himself. He tried again, and this time the flame came almost immediately.
So now he just needed something to distract tin man.
A man flashed in the office and dropped off someone else. Sometimes it was better to be lucky than good. As tin man focused his attention of the new occupant, Feyd slowly stood up and stood near the lock. He focused on bringing the orb to his hand, which had gotten easier every time he tried it, and placed the white hot orb onto the lock, gently pushing it further and further, hoping the subtle creak of hot metal expanding went unnoticed by tin man.
After a few seconds the orb broke through, and Feyd wasted no time throwing it open and bolting straight for the window. He focused on pushing fire out of his hands and threw himself out before he was sure it was even working. He used every fiber of his being to push himself up with the fire. He pushed himself, pushed his jets harder than he ever had before, and he was flying out of the window and spiraling up into the air before he even had time to be thankful that he didn't just end up a messy smear on the pavement below.
He had no idea how he would steer himself, if that was even possible, or how he would land but he would take flying blind to that psychopath and his fancy cage any day of the week.
