Just watched the new episode >.< I really wish it was on more often! And yes I've seen quite a few things about David tennant returning for the 50th anniversary I read an article earlier where this was written: "Tennant and Piper will join the current Doctor and his companion, Matt Smith and Jenna-Louise Coleman, in the anniversary special, reprising their roles for the first time since 2010." It should be pretty awesome to watch if that's true!
