I have already heard the "good doctor"'s announcement. Judging from his words and what he is suspected of doing, he appears to be someone that would not be the most advantageous of allies. He obviously has his talents and his abilities, but his grandiose sense of self pervades even simple conversation.

I would say that I owe him a debt of gratitude for helping you, but that debt will have to be suspended until such time as he can definitively prove that he is what he claims to be, no more, no less.

I do have to wonder though... if the protomateria is gone, and the nethicite has broken and was removed... what is supressing Chaos now?
