Referring to Johnathan's post, I think that the party clearly does not have the same goals. This is fine, mind you, but needs pointing out none the less.

Personally, I just don't feel that Gregory has evolved enough within himself to be able to broaden the lens/scope for him. He is still very much following his own set of goals. Some of which are shared by other party members, such as finding Castillion, but like the majority of the party, he seems to have his own agenda.
