Albert (The Mutant Phase)

Albert was one of the humans survivors after the Mutant Phase attacked the Earth in the 43rd century. At some point, when the Thal scientist Ptolem was discovering what had killed the mutant phase on Earth, he was used by the Daleks as an informant. He alerted them to where the Fifth Doctor was. Albert was ultimately killed by the Daleks. (AUDIO:The Mutant Phase)
