Howling:TARDIS Evolving?

I was confused when looking at the articles, I saw a couple of characters that said they were an "evolved form of a TARDIS". Just a question, and a theory... 1) Does it explain how this is possible? and 2) Do you think that Idris is the evolved form of the Doctor's TARDIS? TheTARDIScontroller 17:19, April 9, 2011 (UTC)
