The Mona Lisa’s altogether graceless and blatant manner was brilliant. Reminiscent of a certain moment in The Shakespeare Code: “You should never meet your heroes.”

The constant “mia bella” got on my nerves, if only because I study Italian and know that unless you’re referring to a member of your family, you use “la mia” or “il mio”, not just “mia” or “mio”. But I’ll let them off. I get ‘Harders’ wasn’t really a linguist. And I can be insufferably pedantic.

The reappearance of the Slitheen – sorry, Blathereen – next week made me feel slightly disappointed. I know that they’re the SJA equivalent of the Daleks, but I’m not sure how they achieved that status. The third series of DW didn’t bring the Daleks in for the finale; couldn’t SJA have done the same?

But overall, loved this week! And anything with Haresh or Gita in is brilliant. And the best moment of the episode was Sarah Jane talking to Mr Smith about motherhood, if only because insights into parenthood in children’s TV are few and far between.
