Mavros looked down at you, collapsed on the ground after he raided yet again another corrupt organisation. But Mavros could read people well, despite your unconscious state, and he could feel you were one of the justice seekers. That was what his group of people were for. They deliver the justice that weren't served, by any means. The things they did were nothing short of rough...but it was all for the greater good.
And the fact that you looked like one of the people who happened to be misplaced in a corrupt organisation meant that he also ordered his men to take you back with them.
"She's awake"
Mavros' husky voice was the first thing you heard when you finally regained consciousness. He spoke calmly, yet there was some sort of silent power hidden in his voice.
"I apologise...you were collateral damage"
