I am only 28 now and have only been watching the show since I was 14. I didn't even know about these characters- Carlo, Cain and Tina. What is the deal with them? I know Tina is Sarah's mom, but that is as far as I know. Just how evil is the Carlo guy? Why is he on the FBI's most wanted list? Who the heck is Cain? Oh, and the biggest question of them all, did Viki really kill some guy- Johnny I think they called him? When was that?
