Heritage
Dale Smith
 The Seventh Doctor and Ace arrive on Heritage in the year 6048 to visit the Heyworths, who are old friends of the Doctor's. Nobody seems to want them on the planet, and certainly not poking their noses in. But they are stuck there until the next day. The Doctor doesn't want to get involved, but Ace can't help herself: by talking to Lee Marks she finds out that the Heyworths were murdered by the townsfolk, because they threatened to disrupt Professor Wakeling's experiments into cloning. Without the cloning technology, Heritage would have nothing going for it at all. The Doctor suspects all this, and also that the Heyworth's surviving daughter Sweetness is a clone of her mother created by Professor Wakeling. What he doesn't tell Ace is that Sweetness's mother is actually his old companion Melanie Bush. The Doctor confronts Wakeling and ruins his chances of announcing his discoveries to the universe. As Wakeling tries to take revenge on the Doctor, he is caught in a landslide and probably killed.
