Alex & Adam
Alex was observant. he had to be, to survive his time in the service. The one time he let his guard down, he lost half his leg. That wasn't going to happen again. He noticed the subtle change, the shift in Adam's posture.
"What is it?" he asked. he didn't realise it was a true change of control, that a whole other presence was taking over. He just knew, recognised, that something shifted in the man in front of him.
