Space

"How can it be her fault?" 

"Because it was my skirt and my husband and your glass floor."

 - The Doctor and Amy

Stephen Moffat has a bit of a habit of writing good Comic Relief episodes, and he's pulled it off again. Space is packed full of witty one liners and is up there with The City of Death as a chuckle-fest.

Moffat is always one for self reference and yet again he's slipped one in -  a cute banana reference harks back to his first Doctor Who script 'The Empty Child' which pops up again in 'The Girl in the Fireplace'.

This micro episode packs a lot of punch for 4 minutes without feeling overcrowded, unlike other episodes we could mention. As it is we get a sweet bit of banter to help ram home Amy and Rory are now a married couple. We get the very funny little scene in which Amy and Rory argue over the former's driving abilities, leading to the great one liner "Where according to Amy there was an unexpected house".

This mini serial also brought up something slightly unexpected; character development. Rory now seems much more at home as a companion than he did last series, and his stammering has almost disappeared. It's nice to see that Moffat treats even the seemingly unimportant episodes as a chance to flesh out his characters.

Whilst past Comic Relief specials have been a bit humorous, in this episode and the one that follows we get a proper trope of laughs. Using the TARDIS set as an opportunity for Rory to look up Amy's skirt is sheer brilliance. Oh and we end on another back reference.
