He didn't need much light to see what was going on, he had found her, and she... was not herself. If anyone had been able to see his face in that moment, it would have hurt to see him; sadness, pain and shock all showing in those bright blue eyes.
Completely disheartened at the view he had in front of him, he simply stood, as if waiting for her to strike, the fact was that he didn't know what to do. He wasn't going to hurt her, not a single bit, and then again, he couldn't let her hurt him, Tifa would get worried, again, for once, he had to stop worrying that woman, but that didn't seem to be the option... Tifa would have to understand, again that he had to do what he had to do.
