Oh, and dont think you know Emmerich just yet. All the fun behind the character comes from the moral conflict and how he feels by his other side.
Its a fight between the 2 personas. Which one will end up winner? The beast or the man?

I can say thst if he finds a woman who he can open his heart to, you will know another man.

Oh, and dont expect Emmerich's second persona to always be this... Dark and bloodthirsty. He is like that because of the full moon, and because its the first time he "gets out" in some time. Emmerich was fighting against it for a long time, repressing him.
