Season three of the Sarah Jane Adventures has recently started airing in the UK on CBBC, and that means we're in count down to where the Doctor drops by for the Marriage of Sarah Jane. New pictures have been released showing the Doctor at the door of the Tardis, reaching for Clyde from the same doorway, several of Sarah Jane wearing a horrible frumpy black outfit (very reserved, almost funerary?) in the Control Room where the Doctor's leaning in that way he does when he doesn't want to say goodbye, and one of the Doctor showing up at the wedding where Sarah Jane is standing with who we presume she's to marry.
This is the start of the countdown to David Tennant's goodbye-- we've got three specials and the Animated Adventure left, and then it's all Matt Smith.
Meanwhile, if you're curious what DT's up to right now, there's a behind the scenes video from Masterpiece Contemporary to watch. In his usual charming way, he speaks of life, acting, Doctor Who and Masterpiece Theatre.
