I also wondered about the two dead agents. On the one hand, Clark has been kidnapped by a maniac, held against his will, and systematically tortured (both physically and mentally) for the past 7 years. Killing in an attempt to escape would be, in my mind, justifiable homicide. On the other hand, it doesn't sound like Clark - especially the maiming of the body and the brutality of the act. So, I'm waiting to see exactly what transpired, and how much of Trask's report is truth, how much delusion, and how much outright lie.
I had the exact same reaction. We all know that Clark just isn't a killer - but he's been provoked and tortured so much... could the leopard change his spots?
It's a measure of Corrina's genius that I'm wondering!
