I think the bigger on the inside has been done to death so glad this dropped that. Though in the Christmas episode you saw her enter then leave and walk round it.

The babies thing seems to be a theme and knowing Russell will be part of the finale reveal, with Ruby's mum and being a foundling like the Doctor.

Boom(Moffats episode) was brilliant. A surprise appearance from the actress set to play the new series 2 companion also.

Clearly something building with the actress that has appeared as a background actor in every episode so far.

First episodes of RTD are usually silly fun.
