One of Doctor Who's unexpected mysteries finally gets explained.
When details began to emerge for last year's Christmas special, The Snowmen, we were really surprised to see Sontaran nurse Strax among the characters appearing. Didn't he die during the battle at Demon's Run? If he didn't die, then how did he survive? And what's he doing in Victorian England with Madame Vastra and Jenny?
Behold -- the answer, at long last, awaits you!
While it may not be the most necessary story, we really enjoy the goofy comedy that Strax brings to the Who formula. Plus, who could say no to more Vastra and Jenny?
