The Hungry Earth was pretty good too, I thought it set up the next part perfectly. Can't wait for next week's!



Interesting. Totally forgot about those two.

Yeah, the thing with crossing his own timeline, is he can't do it to change what has already happened. So he can't go back and warn himself or assistants about future events they didn't already know about at the time of his journey. Whereas if they did, and from him, he would have to. He just can't change an event that's happened in his or an assistants timeline that would change how they have already interacted as it would change their personal timelines and essentially become a mess. So long as that doesn't happen, he can cross timelines all he wants, so long as he doesn't change what happens.

But in the weeping angels case, he didn't change an event that already happened, in fact if that really was him time traveling into it, he's now a fixed point in his own timeline to where he'd have to since he is an event that has already happened to give Amy the confidence to survive.

Time travel gets heady like that.

In theory you can observe your own timeline, you just can't change it, but if your interference is what made your timeline happen the way it did, then you have to interfere.

What's got me confused now though, are (highlight for spoiler)the effects of Rory in the opening episode being different now that he never existed. That means Prisoner 0 couldn't have been caught from Rory's cellphone, as Rory doesn't exist in time anymore.

So does this mean Prisoner 0 happened differently, or could still be free?
So far I'm loving the episodes, but so many new questions are popping up.
Including how can time be re-written? In theory it always could, but at what cost in doing so? Butterfly wings.


And yeah, I loved the Valeyard/Dark Doctor nod. Can't wait for him to show up someday. =D
At least this finally puts one thing to rest. Rose's human Doctor who was born in genocide, is now definitely not the valeyard. They won't use that scapegoat to avoid it. Hopefully this means come in the next 2 regenerations we'll see the birth of the Dark Doctor!


*Edit*
The problem with Rose's Dad is as Follows.

Rose changes her own timeline with the doctor to travel back twice to see him die, and saves him. Nullifying their own timeline of the previous visit, creating a paradox as the previous visit already happened before she saved him. Nullifying those events, and becoming a paradox.

Now with Pete alive in this timeline, her entire life happens differently, to the point she could have never met the doctor, which makes her traveling back in time to save her dad impossible, and the entire thing becomes an even further paradox.

The same happened in the first Master finale with the end of the universe humans coming back in time to replace current humans. This creates an impossible paradox, as since the future is changing the past, the future won't happen the same, therefore they can't travel back to do what they did, and it's another paradox. In this case, the master knew this and had built a paradox machine to circumvent it.

To avoid all this mess, the doctor just doesn't do it.
Like with the runaway bride. The doctor says he couldn't change Donna's timeline to take her to her wedding to get it right.
Which is sort of a lie actually, since she disappeared from the wedding, he can travel to the point she disappeared at, as no one in the timeline would know the difference till she called her mom to tell her she was on earth. At that point she can't go back. As she'd inadvertantly be calling her mom as she's at the altar. I think he was also worried that second donna would have teleported into the tardis of that time just like first donna, and bam paradox yet again. The Hu-on particles would have doubled up as a magnet because of Donna and the tardis attracting the same donna all over again.

Time travel is a really heady concept that creates issues when not handled right.
