Heini

Heini was one of Olga Bordmann's school pupils in Klimtenburg in the 19th century, who helped the Eleventh Doctor collect pieces of a Cyberman Hapthoid reactor unit that had been made into jewellery by Vadim and Nefta and were spreading Hapthoid Radiation Sickness to people that wore them. Heini came to the Doctor and Olga when Lagis proved reluctant to give away her brooch.

Jedka remembered an instance in which Heini had to set a good example. (PROSE: Plague of the Cybermen)
