It may just be me giving it more thought then it's worth, but only one side of the Doctor was exterminated - one heart. Everyone else goes completely X-ray crazy. Their whole body flashes, but with the Doctor only his left side flashed.
BBC iPlayer - Doctor Who: Series 4
Bang on 42 minutes and 37 seconds. Watch. Re-watch. Watch a third time, and see if you agree.
I'd forgotten about the hand, by the way. Now's our chance to finally bring those scriptwriters who have infiltrated the Chrons into the light! Muahaha!!

I'm with Harpo and others who have said things to the same effect - Dalek Caan is
fantastic!

I was giggling all the time he was on.

However, for those spotting "what is the theme this season" I think we've had about everything: stolen/missing planets, the bees, the Medusa Cascade, the Shadow Proclamation... and we finally found what they all meant.
I got one right without Wikipedia'ing it!

And I was right about the Shadow Proclamation being a sort of celestial UN:
- The Shadow Proclamation protects all planets from invasion, like some sort of celestial UN
I was off with my thoughts on Rose being tied in with the SP, and that in the Medusa Cascade new planets are born, though.

I've lost track - was it this week's ep that originally didn't have a published title?
Yep, Tep.

Something I noticed, which I'm very surprised no-one else did - when Harriet Jones, former Prime Minister was calling, there was a familiar tapping noise. Duh-duh duh-duh. The phone signal also went out in two sets of two. And Donna heard it on the steps.
Maybe someone's trying to get into our minds and screw us over? OMGZ, RTD is the Master!

As for my thoughts on the episode... it seemed a bit forced, in my opinion.
And it was nice to see Gwen and Ianto.

Makes you wonder how they defeat the Dalek, because I'm pretty sure both of them (who, and I'm sure it'll make some people happy, worked as a team with Jack) have signed on for TW Series 3, as has Jack.
Sarah Jane, and particularly Mr. Smith, annoyed me. Oh, and why no K-9? He hasn't been killed off, has he?
EDIT: I'd also like to comment that, for once, the finale isn't a London-based one. Hell, it's not even at the Earth's co-ordinates!
But seriously, this series seems to have had much fewer Earth episodes than other series... thought it might just be me.
