I really believe that Scratch is going to kill Liz. Saul will find them. She will go "It is 2 of the 3 people that took the tankers. What? You are an item? Well in that case..."

I remember at the old forums, right before season two started, there was a "Theories on Season 2" thread. KC made a post with only one line in it.. "If you hate Scratch now wait untill next season" or something to that effect. I think Scratch is going to be the death of Lizzy in some fashion.
