Yo Nik. Slapping down my idea on WND without listening properly. Not cool man, not cool.
I said that he gives off a DIFFERENT smell not no smell. If there are enough different hormones etc floating round in his blood brought on by the Skunken change then he would have different smelling sweat.
You can get different smelling sweat based on what you eat and medications you might be taking, and you can also smell different depending on you mental state, fear etc.
Thank-you for listening.
