Beck's struggling stopped as soon as the scientist's words were spoken. He vaguely recognised that she was the same person whom had been outside the cage when he woke up. Naturally he felt the urge to yell out an insult of some kind, but the sight of the needle seemed to freeze his entire body. The warmth in his system seemed to drain out of him, as if someone had just dunked him slowly in ice or poured freezing water over his head. He wasn't scared of needles, but he most definetely wasn't the biggest fan of them. It didn't help that whatever she would be injecting into him wasn't certified as safe and was going to turn him into some sort of unnatural monster.
The teen twitched a little as she came closed, liquid visibile inside the tube of plastic. The strange colour was curious and had the situation been reversed he himself would have wanted to investigate what it could do. Though he'd use methods more humane...more or less. Scientific discoveries were fascinating, but that didn't stop the arrogant boy from hating what was going on. When the woman reached him, injection poised, his brown orbs widened and his eyebrows rose. He tried to back away, but the shock of the sight of the needle hadn't worn off and the guard easily held him in place.
The scientist tilted her hand, pointing the tip of the sharp object towards him. The guard thrust his arm forward and held it there. It was lifted horizontally in midair in almost an identical position to how it would be after punching someone. Beck really wanted to punch and kick at these people; to get away before they got him and turned him into a beast. The arm quivered slightly, as did his entire body, and the woman rolled his sleeve up. He turned his head to look away, but not in time. He saw a glimse of the metal pushing into the flesh of his arm. He almost immediately felt the effects. An icy yet burning pain spread into his arm as the liquid was injected and the muscle jerked. It began to spread down his arm and across his body. He screamed.
(I've always had in mind that his injection and transformations would be painful, at least at the beginning, and that he wouldn't be able to keep his thoughts together as a wolf. Hope that's okay for a little bit of difference :3 He's not turning yet, just reacting to the jab. He'll turn into a wolf in my next post though
