The search for Jack is on, and Jenna feels as though it's her fault that he is missing. Pam is hell bent on continuing Bobby's Emerald mining deal w/ Matt Cantrell. So much that she buys J.R. out of his share to go out on it alone. Ray and Clayton go into the horse breeding business, and to Ray's bewilderment Clayton already wants to speed up production. Suspiciously, Jack's blood is a perfect match w/ Jamie's. Maybe he's a true Ewing after all, but what does this mean for J.R. "co venture" w/ Angelica?
