Big episode for a couple of reasons. Flashback for John Locke reveals his parents are  f u c k e d  up. His birth mother was in mental hospital and his birth father cons John out of his kidney and then bails on him. What's worst is that he put his mother up to it to get the long con started. Ouch. I'd go ballistic and do some serious damage for sure. Also, John convinces Boone to climp to the Beechcraft that's stuck in the trees only to have it tip over and crash down below. We all know how this ends.

John Locke is bad news for sure. Stay away.
