Sozin nodded, and would get himself started. Right in - cleaning his body, much in a similar way to the temples. It was an act of sanctity: though cleaned, the sauna and the springs were not for dirty guests. The baths next to the bath were for the cleaning, where they could scrub away. On the little bucket, even as far as to scrub himself down, and pouring the bucket of lukewarm water over his head: wetting his hair, he would run a hand through it and slick it back, and wiped the excess water from his eyes and face, taking a breath as he finished.
In he went as well: without much need for clothing at this point, he'd dropped the towel with some slight disregard, perhaps a purview of his personality - by the personal tub itself. He had placed in a bag of salts, and so the smell of lavender permeated most strongly: salt and the purple flower milling around the surface of the hot water. Ran on the other hand would be doing something.
Ran would have seen the back of his head, as she came in - she had been all too aware of the possibility of a perverseness and had reacted accordingly - and Sozin didn't blame her.
Ran might've been able to appreciate that Sozin kept his eyes shut until a few seconds after the water had stopped sloshing and making noise, he remained quiet: letting his nose fill with the warmness and right through into his lungs. It was permeating right through his body, sapping out the kinks of his muscles.
Rather than stare at her, he move his body outward, so he could lean the nape of his neck against the back of the darker wood material, to look up at the ceiling. He did breath, too: it was a sound of relief. She may or may not have known or be able to tell that he had not been in one of these in a long time.
It was such a... mortal thing.
"Is tea what you really do?" Sozin asked. His voice was a bit shy of usual - on account of his head being wrung back and it made him sound a bit more nasally.
"I spent a lot of my life liking it before I did not. I do know that it's common enough that you need field upon field... and you do not strike me as the wholesale type." If she was a bit naughty... well, he did not mind a bit naughty.
Sozin's dark whispered creeped in - While she would find her existing emotions, whether distrust, hate or lust - amplified. Only a little. But in the back of her mind, too, there would be the critters of deception feeding her little lies in her own voice: not real words, of course: but those fed by her emotions. He could be as polite as he liked in the meanwhile.
A boon granted to all of the Followers of Akui is their ability to subtly manipulate individuals; to emit a dark of feeling of dread and coldness (when they wish) and also exists to heighten the target's existing feelings so that they can be slowly proselytize them.
