Time

"I'd give you your driving license"
"Hmm I bet you would."
- Amy and ...Amy.

This time we only have 3:00 and still a lot is going on. Now that everyone is doomed from the TARDIS materialising within itself (which does make for a pretty cool effect in the last episode), we now have Amy flirting with herself. As if things weren't complicated enough, the prospect of two Amy's certainly get's Rory red in the face. See what I did there? Oh never mind.

Not quite as many chuckles as the first part but still overall a funny little nugget of Who goodness. Considering Moffat has created a neutered Doctor he does like writing sex into his scripts. Okay it's hardly pornography but many less than subtle lines creep in. Of course we don't care because it's a clever little script.

The script quickly  gets confused with itself in terms of timing. Whereas before transition between the box and the interior doors was instantaneous (even being able to wave in real time) the timing quickly gets diluted so that one box is running ahead of the other, with not much in the way of an explanation. It really does feel as if the Moffman got stuck at this point and just started making it up. It's a shame because it's still an interesting concept just a bit... mishandled.

Luckily the main reason to show anything off on Comic Relief is humour and this mini serial delivers, ending on a brilliant line. Roll on The Impossible Astronaut.
