Prowl stalked into the Decepticon brig irritably with his wings hiked up. The head guard had informed him of a mech whose spark energy was within an acceptable variance of his criteria, if not close enough for surety. As always, three Praxian enforcers followed him silently. He paused as he saw three of the hulking guards holding down a much smaller Polyhexian-framed Autobot, apparently the one the head guard had singled out. Prowl took the time to look more closely. The Autobot's frame was a sturdy but flexible model, without the heavy armor so many added. Prowl decided he must depend more on his speed and flexibility to survive and was likely a special operations' agent. Prowl was pleased. It had become much more likely that this was the one he was searching for.
As Prowl began stalking forward again, the Polyhexian saw him. Prowl watched as his struggles increased, wild thrashings that the three guards struggled to keep contained. Stronger then he looks, Prowl mused to himself before looking for the mech that had alerted him.
"This is the mech?" he asked the head guard evenly, face expressionless. The large warframe fell over himself to explain to the much smaller Praxian. He told of how they had found the infiltrator and the head guard himself had scanned his spark for a match. Of how he had immediately, without delay even, sent the message. The Autobot had been kept safe, undamaged, for Prowl's arrival. Prowl nodded gravely. The Autobot had stopped struggling during the head guard's report. He was venting heavily, but also listening intently to the discussion between the guard and Prowl.
"You scanned through armor?" he asked. The head guard nodded quickly. "The match may be closer without the interference of his armor. Open him." For a moment both the guards and the Autobot seemed frozen before the Polyhexian cried out in protest and thrashed even more wildly than before. The guards almost lost control of his twisting limbs before regaining their grip and forcing him down to the ground. The desperate pleas and denials of the Autobot turned into shrieks of pain, as heavy claws forced his chassis open. They rose to a painfully high pitch before cutting off abruptly as the Autobot went limp.
The head guard pulled out the spark scanner and gingerly scanned the exposed spark of the unconscious Autobot as Prowl watched. When the results came back as a perfect match, the Praxian smiled.
"Have Hook repair him before taking him to my quarters," the Decepticon Third in command said.
