Ace To Finally Leave The Doctor?

Sophie Aldred, who has appeared in over 20 audios as Ace, as well as appearing as the last companion of the classic series has apparantly quit the role and will make her last appearance in the April 2011 release, Thin Ice.

The story, which features the Ice Warriors, is an adaptation of an episode called Ice Time which was written for the unmade 27th series which would have originally seen Ace leave the Doctor to train to be a Time Lady on Gallifrey. Whether this will still be the outcome or whether she will leave to set up her charity as hinted in the SJA episode Death Of The Doctor is unknown.
