Rowan was released by the man holding him, realizing that person was the same one Arryn greeted that night. He then looked at the people holding guns to the faces of the real Hellhounds. He could recognize all of them because they were half of the injured he patched up that time. That was also how he figured out that the driver and the companion were from that family.
It was easy to just kill the man then and there. However, he looked at the destroyed expressway behind them and the debris it created meters beneath them. He could even distinguish a few limbs sticking out of the broken cars.
"No. Killing him with a gun was too merciful." Rowan turned to face the other Hellhounds. "…I gave you guys a chance to live, and you still decided to reap lives, just like before. I'm not obligated to fix you one more time. You decided to serve your family well, so just die as one of them."
