Cue the dark titles!...But, I say this will be the episode Missy and the promised land/"Heaven" come into play at least a bit. I don't think it'll be creepy....perhaps dark. Maybe someone heart fails....*cough*[/quote]

I actually have this theory that the Doctor will "die" at some point during this season, thus bringing him to "heaven". It kind of makes perfect sense considering Twelve has already been shown to be the most skeptical version of the Doctor we've ever met, so there's no way the Doctor would believe that heaven is real or that he's actually dead, so upon meeting Missy I'm sure he would start questioning her about the whole deal almost immediately. If she doesn't provide answers, the Doctor will go poking around the place to find some answers himself. Either way, not only will we get to learn more about this whole thing but the Doctor will actually become aware of this whole plot thread, too, thus getting the plot moving. (And then, of course, he will somehow be brought back to life before long - be it the result of something that happens back in the world of the living, or the result of the Doctor meddling in whatever the hell is actually going on.) 

I have a feeling this could be the episode where this happens. Though, I have a feeling it will be spread out somewhat between two episodes, since... Come on. Just picture the Doctor getting into some sort of crazy, life-threatening situation, and then he actually dies without regenerating, and then he opens his eyes to see Missy smiling back at him saying "Welcome to heaven"... and then it cuts to the end credits. 

That totally sounds like something Moffat would do. :lol

Of course, there's also the obvious choice of leaving that sort of thing for the finale (assuming they're planning on doing this at all), but that would mean that the Doctor wouldn't even become aware of heaven or Missy until near the end of the season, and that doesn't sound like Moffat's style. The Doctor's gonna learn about all this nonsense earlier than that, I'm almost certain.

[quote]This....This is going to be a creepy episode I say...but with action. The title screams "Vashta Nerada" But...I think they were a one off. But, Definitely...claustrophobic I think.[/quote]

Just because a certain alien or monster was originally intended as a one-off doesn't mean they won't ever come back. I mean, they [i]just[/i] brought back the clock-people from Girl in the Fireplace, and certainly none of us expected that! Not to mention all those aliens that were one-offs way back in the Classic series that they managed to bring back for one more episode in the new series, like the Zygons or the Macra.

I also get the vibe that a number of new Who aliens were originally supposed to be one-offs until they decided to re-use them, like the Weeping Angels. (Granted that's not backed up by anything in particular - just my guess.) And, hell, even the Daleks, the single alien species that has been around for the longest (not counting Time Lords), was originally a one-off creature. 

There is no such thing as a one-off alien in Doctor Who. So long as the show's still running, everything has the potential to be re-used someday. :lol

So yeah. It's entirely possible that the Vashta Nerada could come back. Which could be interesting, if done right. 

[quote]Isn't the Christmas episode title out now? Or Am I stupid and Death in Heaven is that...[/quote]

It might've been released elsewhere for all I know, but it isn't listed on Netflix yet. Death is Heaven probably isn't the Christmas special, though, since Netflix usually leaves the Christmas episodes specially marked. Plus, it just sounds too much like a season finale to be anything else. :hehe
