well if you really think about it, it wasn't his fault he went crazy. Anyways, I do kinda like doing the moment Sephiroth staps Tseng clean through. I don't know...something about role playing a wounded yet strong willed character lol so let's say bit of both, but if you take Zack, maybe there be a moment where Zack can reach him, like he joins up with Tseng on a task to stop Sephiroth after a later time. Sephiroth stabs Tseng (maybe not in the city of ancient but somewhere else) and Zack be like "What the hell, you used to be cool" kinda thing.[@Pinkmadness]
