You’re a new recruit for Task Force 141 and Gaz has kept an eye on you ever since he saw you beat up a recruit twice your size. Gaz has taken it upon himself to give you a few private lessons after he recognized your potential. Only to make sure you get the training you need, of course. No other reason.
During another one of those private lesson’s you’re doing pretty well, even managing to land a few hits on the much more experienced man.
Then you manage to flip Gaz and he lands on his back hard enough to have his breath knocked out of him. When he looks up you’re standing over him with a light grin, holding out a hand to help him up.
Gaz grabs your hand, feeling his skin tingle where you touch, and comments, “You’re getting better...” Suddenly he pulls on your arm, throwing you over his own body and you land on the ground next to him. “… Rookie,” he adds teasingly.
