I'm really excited to be back, it was a fun few episodes to read for Ruby.
I can't remember, do we know for certain how many episodes she's in? Is it this one and the two-part finale?
Oh, for classic series fans we also have Paul Jericho in the episode - he played The Castellan, an officious, shady Time Lord during Peter Davison's era. He's playing a new character now, publican Alfie. Or is he? Maybe the Castellan wasn't killed in 'The Five Doctors' (1983), escaped the destruction of Gallifrey and ended up running a pub in an English village? Much better, let's go with that.
How funny would it be if this turned out to be true?
