The only one even vaguely capable is... well, the emotional Roman, to stay cagey.
I like that they all have their own, personal dilemmas. That's very clever. Heck, 'salmost the opposite of what The Stolen Earth did.
The series 4 finale just conspired to draw all the characters together. Usually along the lines of "ragh, Daleks!"
Actually, just for a second, when the door cracked open to the tune of a Dalek voice, I was worried it was gonna take the form of Army of Ghosts, and it'd turn out that it was just Daleks inside.
ALSO. In retrospect, those scenes in The Eleventh Hour and particularly Flesh and Stone, where Prisoner Zero and the Weeping Angels laugh at the Doctor not knowing what the Pandorica was... take on a REALLY sinister tone.
I'm actually at the point where I don't want to speculate for next week. I don't want to deconstruct and I don't want a single preview clip. I just want to sit down on Saturday and have all my presents at once. I don't even have the faintest hint what tone the next episode might take, or where it'll be set, or anything like that. Very 'citing.
