Cloud had to agree about the possibility of a chocobo - and he would have disagreed if he'd know of her evil designs on his voice mail. It was distracting though and he didn't mind distracting. As they'd shown earlier, stealth wasn't really their thing when they were together and he'd rather hear her voice than the ones just out of range of his hearing at all the windows. When Yuffie slipped into one of the side rooms, he followed, curious, but when she pressed her face to the window too close, much too close to that fog he reached out an instinctive hand to her shoulder to pull her back. It was his bad hand. He hadn't been thinking. Luckily she turned back to him before he touched her with it though and so he withdrew it, letting it drop against his side.

He'd been trying his level best to not notice the fog. Though, if Yuffie was catching it too, maybe it wasn't just him?

"Fog's been creepy since we hit the tower. Maybe before." As he spoke the window creaked the littlest bit. As if something on the other side of the glass was trying to press inward past it, even though they were too many floors up for anyone to be there with nothing to support them.
