Just one thing: How do we know that Anne's ans William's surname is Pratt?¿ In the episode Lies My Parents Told Me it doesn´t appear in the credits...Does someone know the reason why?¿ thanks. --- Trebio. November 17, 2009.
One of the Spike IDW comics lists her surname as Pratt. So far there has no been any canonical material contradicting it, so it can stick.--Gonzalo84 20:07, November 18, 2009 (UTC)
