Yeah, yeah, yeah... Merry Christmas and all that, but I think we've kind of papered over the more important issue here: This is it, people. The final two episodes of David Tennant and the Tenth Doctor, not to mention the current TARDIS, Sonic Screwdriver, Head Writer and the Logo as well. Described by Tennant as "A Tale of Gods, but Gods who are fallible", the two parter features the Return of John Simm as The Master as the Tenth Doctor's final days play out. This is set up to be the greatest, grandest and most perilous episode of Doctor Who since it rebooted in 2005. I can't believe it's almost over. *sniff* This will be fun.
