Ben said that he died. The Ben we have here is a clone of the original Ben. The real question is who cloned Ben? I think Warren is around here somewhere as, like you described, Jackal Prime. But the idea that he may actually be somewhat unstable upstairs is possible. I don't exactly feel comfortable with the new Ben, I am suspicious of him for sure, though, or at least I think someone is ready to cut his strings, so to speak.
