SPOILER ALERT: This weekly blog is for those who have been watching the new series of Doctor Who. Don't read ahead if you haven't seen episode two – Day of the Moon

Dan Martin's episode one blog

"We are not fighting an alien invasion; we are leading a revolution."

Not everyone was so ecstatically thrilled with The Impossible Astronaut last week as this blogger – with the biggest criticism being it was all a bit talky and revelations were thrown in so thick and fast that by the time Amy announced her pregnancy it was becoming an effort to care. There's every chance that those who felt that way, probably won't be re-assured by the concluding half of this caper, which answered a handful of questions before throwing up double that number – and that's before the final cliffhanger where the little girl regenerates.

After last week's rapid-fire of plot swerves, if I have one criticism of Day Of The Moon it's that it maybe sags a little around the middle. But that is perhaps scouring for criticisms simply for the sake of levity. Last week's cue-cards were thrown away in favour of action, tension, horror and River Song in a business suit.

You might pick holes in quite how easily Canton knew what to make the Silence say, and just when was the right moment to send the video file to the Doctor, who was waiting to hack into the feed of the moon landing. You might also question whether – when you already have the President on your side – faking imprisonment in Area 51 and sending your friends on the run for three months while the rogue FBI operative builds you a soundproof base made of Zero Balance Dwarfstar Alloy might be a touch over-precautious.

But if they hadn't done all that, you wouldn't have got that incredible sequence of all three companions "dying", the Canton reveal, an amazing swimming pool gag and that wonderful FX shot of Apollo 11. And those moments are what this show is really about.

"You should kill us all on sight!"

The Silence are apparently banished by some standard Moffat phone-call trickery (a move he's been pulling since the one with the corrupt councillor in Press Gang) but that can't be the last we've seen of them. For one, we've still no idea of their motivation. All we really know is that they've been standing behind us for all eternity, controlling our behaviour through post-hypnotic suggestion. But is that really all that bad?

What if they had been treating us like performing monkeys, having us do cute, daft stuff like invent Rastamouse, grow vegetables that look like willies and commission Outcasts, just for kicks? The only really bad thing they've done is kill Joy in the toilets, and it's possible that was a rogue Silent just as we have rogue murderous humans. Obviously I doubt very much doubt that's the case, but you know what I mean. More Silence please!

"Aren't you forgetting something?"

Oh yes, the inevitable hoo-ha about the Doctor finally full-on pashing River Song, with the strong implication it's happened many times before. There are plenty that want a sexless Doctor, but that's another blog entirely. It's is worth noting that it's never actually been stated out loud that he has no libido. We've just never seen it. But then hardly anybody's libidos got shown on television in the 1970s.

Fear Factor

A properly disturbing horror sequence as Amy and Canton visit the abandoned children's home, riffing magnificently off Batman's Arkham Asylum. Doomed daubings all over the walls, a warden with a melted brain, and the sudden emergence of a whole load of tally markings all over Amy's face. Shudder.

Mysteries and Questions

I have a theory about the baby, based on a snippet from a Karen Gillan interview. She told Radio Times that there's one line that sounds throwaway hidden somewhere that might just be the most significant thing she's ever said. Sticking my neck out, I think it could be the line about the baby: "What if it's got a, a Timehead or something. Whatever a Timehead is."

Well, maybe Amy's gag hit it on the head and the answer is hidden in plain sight. Whatever a Timehead is, it can't be good. Maybe somebody with a Timehead is a bit like a Timelord. Maybe it can even regenerate. And Amy is about to birth a new breed of Timelord, who entire empires would rip the universe apart to get to.

Time-space debris

• Canton Everett Delaware III, revealed as a gun-toting homosexual. Do we smell a potential love interest for Captain Jack here?

• Perhaps the biggest "what!" moment of them all, as Amy creeps through the children's home, a shutter opens with a lady in a funny eyemask: "No I think she's just dreaming."

• More general badassery from River, yet the finest moment comes as her heart breaks with the realisation she will never kiss the Doctor again.

• "I've got a screwdriver!" "Go and build a cabinet then!"

• "Say hello to David Frost for me." And yet Moffat's drawing of Nixon is still nothing but likeable.

Next Week!

A bit of light relief on a pirate ship, as Hugh Bonneville and Lily Cole guest star in The Curse Of The Black Spot.
