Loved so much about this episode. Adore that Nefertiti gets to see other time periods and live a different life. She rocked in every way.

I think that the companions can only travel for so long before wanting to go home...er, to whatever home is for them. It's hard to swallow all of space of time for every meal. Even the Doctor struggles with that. This is what I'm telling myself so that I don't feel sad that the Ponds spend months away from Eleven and the TARDIS.
