Alex O'Loughlin's apperance in the show

As we can see Alex O'Loughlin's appearance in Criminal Minds was an outstanding new for most of his followers.
In the show, he played the role of a man whsaw how his father killed his mother and because of that decided to kill women the same way his father did. This didn't las long until he found a boy who he felt identified with.
Personally, I saw the episode and I could see that he did a really good role. He really caught my attention.
