Noiz takes a cup and holds it in both hands firmly, blowing on the surface for the sake of appearance before bringing it to his lips and taking a sip. The liquid seems to be hotter than he expects, because even knowing it would be hot, it still startles him enough that the hiss he lets out seems natural and convincing. Not that Proto would be able to gauge as perceptively as a human would. His lips and nose crinkle and he pulls back.

"Hot." It sears the tip of his tongue, the aftermath of heat making it tingle sensitively even when pressing his tongue against something. Mouth burns are annoying. But at least the temperature perception there acts as a casual reminder that yes, some part of him really is alive. The ability to perceive changes in temperature is linked enough to one's sense of pain that everywhere else mostly all feels the same no matter how hot or cold.
