Who is Nathan's biggest enemy?

i honestly don't think nathan really has any enemies...he's the kind of person who is his own worst enemy...but i really don't think he has any.

Right now its that stupid whore Renee who wants to ruin his life, reputation and career just so can earn a few bucks =(

1.- Chris Keller
2.- Renee

It was Lucas and now it isn't
