Vala'Keer's supply of oxygen was running low. As the few minutes passed, his slowly began burning. While he could stay submerged longer than any other creature that walked the ground, that doesn't mean he can stay more than five to ten minutes. Eventually, he kicked off, swimming downstream. Like any lizard, his arms and legs were pinned to his side and tail, his whole body wiggling back and forth like a snake or an alligator, swimming by spearing through the water with head, tail bushing him like a fish's fin. 

As he swam downstream, he noticed something falling in the slightly murky water. He caught legs and a face before he jerked away, grabbing the bottom to observe. A human, or so it seemed, struggling with the current and the water, clearly not being able to swim. The Blademaster's vision began going red, but he forced the urge to tear and break out, taking in the apparently naked victim-of-the-water. He watched impassively, hatred boiling deep, before darting up. He broke the surface of the water behind her, his nostrils flaring open and multiple deep breaths, before he shot forward towards the struggling human. His hands grasped a shoulder and the human's side, and he pushed himself towards the opposite shore. Reaching it quickly, he planted his feet, turned his tail to keep it from the water persistently pushing him, and he tossed the human out of the water, to the somewhat rocky, sandy, grassy, shore. 

Her well-being didn't matter- only what she might know. He didn't give her a chance to even cry out before he was out of the water and towering over her. Murder shone in his eyes, and yet he didn't lift a claw to gut her. Instead, he pointed at her, and the pointed down at the ground, trying to tell her to 'stay.' Hopefully, the claws and the array of throwing axes, swords, light waraxes, and throwing knives studded across his body would mark him as someone she wouldn't defy. He surveyed the area, before stomping over the wet girl in search of prey, hopefully a deer. A hide would do well to cover her- she was his charge, and while he may be a monster in their eyes, he wouldn't let anyone under his care, prisoner or no, die of cold or lack of food.

He didn't think she could escape very well, anyways.
