"What exactly were you thinking!" he growled. "You know you are not allowed to converse with any of the homunculi. Do you know how much trouble you could get yourself into by allowing Lust to escape!"
"Frankly, Sir, if I hadn't have allowed her to stay for just a little while, I wouldn't have been able to slip a tracking device onto her person." She said solemnly. Mustang was slightly taken aback.
"You slipped a tracking device onto her person…?"
Sin closed her eyes. "Yes, Sir. I threw her against the wall with my abilities, thus activating one, possible two, of my air-borne molecular tracking devices. They are impossible to identify, even by the strongest alchemic means."
"I see…" he whispered. "Still…you took a great risk, Kraya." Sin's eyes flew open at the mention of her name. Mustang brushed a lock of pitch-black hair from her pale white face with a gloved hand. "Remember, Kraya, you are not the homunculus you once were; never forget that. If you do, it could be the end of you. Even though Lust cannot overpower you, she can." Sin tensed. She knew who Mustang was talking about. "You don't have to act brave in front of me, Kraya. I know the real you, the human you. I was the one who found you that rainy day in the back alley, wasn't I?"
"You were new to the Military then," she whispered.
He nodded. "It was only my first month in the Military, and finding you was not part of my assignment that day."
