Sephiroth stands and lets the water slough off of him. It's not that Reno's nudity bothers him, nor does he make any kind of effort to cover up his own. Rather, it's the fact that his objective has been compromised since the water is no longer clean. So he stands tall in the tub since there isn't room for them both outside of it, all six and a half plus feet of him in addition to the hair dripping wet. In truth, his head is nearer to the low ceiling anywhere in this place than he'd like and he just about has to stoop to make it through the doorways.

The water sloshes around Sephiroth's feet and there is the constant trickling noise where it drips from his hair or down his body. His hair sticks to him in places and overall it's a sight that few outside a ShinRa laboratory have ever seen. Sephiroth is the SOLDIER, after all, and has always been treated as such. Having been conditioned thusly, he pays no mind to his own or Reno's nudity and very simply watches him dry off as if he were doing any other mundane activity.

Sephiroth says nothing, only waits.
