Has anyone here seen Buffy the Vampire Slayer? Originally, there was only supposed to be one. She died and another arrived to take her place but she was revived and so the floodgates were broken. Suddenly, there was a whole world full of Slayer potentials.

I realize Riku never died, but his heart HAD wavered between light and dark and my sig suggests. Because of this, the Keyblade chose Sora as its next wielder. By the end of CoM, Riku realizes he needn't worry about the darkness in his heart controlling him. Knowing that Light and Darkness are merely two pure sides to the same heart, he is able to reclaim his title has Keymaster.

Sora and BK two sides of one heart? I don't know what to say.
The dual-wielding is easy enough for me to theorize on. It's possible that Keymasters are naturally gifted with the Drive ability. Only Sora wasn't the original target of the Keyblade. Perhaps Riku could've done this on his own had he not let his darkness rule him. I think that the strenght of a Keymaster's heart allows him to dual-wield, which is why he merges his heart with the hearts of fellow warriors. As for BK, I don't know if he Drives or not . . . maybe his heart is stronger like Riku's.

I wish I could see Deep Dive. Where can I see that?
I've only seen Another Side . . . Another Story . . .
I thought that Riku was the one fighting the Neoheartless. When I saw him in Nobody gear on the CoM commercial ad I was certain it must be him.
