D roasts everyone in KL. This act is now considered the proof of apparently many folks thoughts that her arc was to go to the dark side.

But I don't believe for one second that any of those peeps envisioned that she would perpetrate that particular act. They had some idea that something would happen to show her dark side but not that.

My point, which is subtle and maybe odd, is that exact act was not predicted by anyone, so it seems, and neither did many people like myself and so it appears too odd and ultimately disappointing.

I'm not saying going bad was unexpected nor that it wasn't a good arc. I'm specifically talking about the burning and destruction of everyone. Another way of showing the change would have worked.

To be honest, it's difficult to explain my point, but I've given it a go.
