Talk:Sontaran breeding planet

How do we actually know the Sontaran Breeding Planet was stolen by the Daleks and placed in the Medusa Cascade? There's no reference to this in The Sontaran Stratagem, The Poison Sky, The Stolen Earth or Journey's End. They mentioned the other previously mentioned missing planets (Poosh, Pyrovillia, Adipose 3) so why not mention the Sontaran Breeding Planet? It doesn't make sense. Will101 20:42, 28 July 2009 (UTC)
