Artyom just sat there as Jack completely ignored what he had said and decided to get all friendly with Maria. He only felt even more so when Gabriel came in he figured. Now there's someone whom knows when to leave something alone. Yet that thought completely disappeared. When he too wanted to get to know Maria. At least Gabriel not being overly nice or exited about meeting someone. Also, the way he carried himself. Definitely some obedience and something happened in his life to make him how he carries himself. Maybe something military. Or even a task force like his own? granted Artyom did not turn out how Gabriel was. Artyom was far more serious. Yet did not hold himself like so. He would keep and eye on these Gabriel and Jack, figures... they obviously know one another.
