'A coward?' Sephiroth mused. 'If cowardice is taking the path most likely to achieve my goals, then perhaps.'
He raised his wing high, black feathers falling in clouds around him.
'We may meet again. Perhaps as allies. That would indeed be interesting.'
With that, Sephiroth vanished.
Reappearing near Gilgamesh, floating just above his battle, Sephiroth whispered, so that only he would hear: 'I still intend to make use of this alliance. But you should know that I know my purpose now.'
Leaving those words to his ally, Sephiroth descended to Sable next. 'I feel that you have changed me,' he said. 'If that comes to hinder my objectives, then know that you and I will meet either as friends or to fight once more.'
Then, Sephiroth disappeared, sending himself to a quiet space of nowhere.
OoC: I'm off again, guess I'll be back tomorrow or something

as a villain? Maybe. We'll see if anyone can persuade Sephy otherwise.
