To be honest, I was eagerly anticipating some sort of change in Shang's psyche, especially since he behaves like an emo teenager despite being almost a thousand years old. But it is just more power.
It feels like we’re drawing near a turning point for Shang. At least I hope so, he’s been emo for a couple of centuries too long now. If this isn’t the time for character development I’m not sure what is.
