Dr. Nick Toscani
Not only an annoying fnck who takes over almost the entire show, he's a condescending prick who yells at everybody, judging them and telling them what to do. He's also an extremely confusing character who causes even more confusing storylines. His personality and background seems to change every minute or they add random stuff out of nowhere. Is he in love with Fallon, is he in love with Krystle, or is he not in love with either of them and just out for revenge on Blake? Or maybe Blake is in love with him, because it seems everyone has the hots for this ugly creep!
The stupid thing is that he's completely unnecessary, take him out of the show and every storyline would still be the same. God knows who desperately tried to push this guy.
