Melanie Bush

Mel Bush was from Earth, and it is not known how she met the Doctor, because he first saw her when in The Trial of a Time Lord, he presented his case and it went into the future, so it i not known when or how they meet. Melanie tended to scream at almost anything and she witnessed the Doctor regenerate into his seventh body. Melanie only stayed with the Doctor for a while and she got a lift back to Earth by Sabalom Glitz, in his new spacecraft which was home to Ice World (Where the Doctor first met Ace and he met Sabalom Glitz there again).

Mel Bush was in The Trail of a Time Lord: Episode 9 (Terror of the Vervoids) to Dragonfire.
