Derek found Midge and Shreela Govindia, two other humans who were being hunted by the Cheetah People. Ace helped them try to catch a Cheetah Person but she failed, instead, they caught the Seventh Doctor and Sergeant Paterson.

When Ace became infected with the Cheetah Virus, she helped them get home. Derek was grateful and said, "Thanks Doctor, thanks Ace," unlike Paterson who just walked away. (TV: Survival)
