Well, THAT was certainly unexpected... he turned on his own teammates, but didn't let Vatti kill them either. The Golds have now captured all of them, however. I think it's a good thing that Pandora and Sheina stepped in when they did, and that the Golds came in when they did. This means they now won't have time to worry about killing one another... they're having to deal with the reality of being captured. This means no one is going to die by the hand of a friend for now, at least.
I really think you're getting better at these unexpected twists. You're avoiding a lot of the typical scenarios and stereotypes.
