After everyone on the island besides Skinsale, Leela and the Doctor was killed by a Rutan scout, they went to the lamp gallery. When the Doctor injured the scout with a make shift mortar, the Doctor asked Skinsale if he had any diamonds, but Skinsale remembered that Palmerdale kept diamonds in his pocket, but Palmerdale's body was in the crew room, so Skinslale went with the Doctor to the crew room. Skinsale found the bag of diamonds on Palmerdale's body, and the Doctor dumped all but one of the diamonds on the floor. While he was picking the diamonds up, the Rutan killed Skinsale as its final victim. The Doctor told Leela that he died with honour. (TV: Horror of Fang Rock)
