Alright, this one was very expected. BUT, if you're doing a David Tennant series, the Doctor is sort of necessary.
I won't tell you all about the Doctor, since you know already. And if you don't, what are you doing here when you could be discovering Doctor Who?! Jeeez...AND OMG THIS IS MY 300TH DEVIATION!
Rest of the Series! Vworp vworp vworp...
