Lost's Bernard (the lesser-seen half of the Rose and Bernard coupling) will appear in next week's two-hour Dallas season finale in a key role that should resolve the mystery of what happened to the original Pam Ewing.Sam Anderson will assume the role of Pam's plastic surgeon, Dr. David Gordon.
The character was last seen in 1988 when Pam (then played by Margaret Michaels after Victoria Principal's departure) informed brother Cliff that she never wanted to see her family again and had fallen in love with her doctor. After Cliff left, Pam turned to Dr. Gordon and revealed the real reason she gave Cliff the brush off: she was dying and didn't want to burden Bobby and Christopher with another painful goodbye.
Dallas producers told me they made an attempt to locate the actor who originally played Dr. Gordon but were unable to find him.
