Showdown of Fate

Cloud: やっと会えたな (At last we meet)
Sephiroth: 俺も探していた (I'm been looking for you, too)

This is wrong. There are, in fact, two things* wrong with Kingdom Hearts, and this is the other one. Sephiroth is poetic, and overly decorates his speech. Notably, he uses 私 as his first person pronoun. Here, he has fallen to the standard video game convention of everyone being a brash youngster.

It's ok, though. The fight scene that follows makes up for this faux pas.

* The first thing that's wrong is that Sephiroth is voiced by Lance Bass.
