The Doctor's travelled forward 100 trillion years, to when most of the stars are going out.

Yeah I first noticed that a few eps back I wondered if she might be the original, but then decided that the original would be older. I remember that when Dolly first became famous that there were popular explanations that clones tended to get organ damage and such compared to the originals.

Thanks, Victor. That's what I was wondering, because they specifically showed Clara counting out the doctors she has known.

Does anyone think that is the last time we're going to see River Song? It certainly felt like a good-bye to the character to me.

I think I have decided to make today the day I catch up on Orphan Black. See you in a few hours.

That's what I thought about the goodbye scene with River, sj.

I liked the ep and am looking forward to seeing how John Hurt fits in all this mess. I haven't really been all that taken with the second half of the season. I like Clara, but the stories, something... I don't know. Anyway, now I'm even more excited fr the 50th Anniv episode. Sad to realize its not unti November, though.

Also excited for the non-Who promo with Tennant and Darville in the murder show. But that's a different thread. I imagine. Didn't see space ships or capes.

I mainlined Orphan Black over the last couple of weeks. So good. How they keep the funny going with Alison and it still fits in with the rest of the show is fantastic.

I really admire how Alison being the comic relief doesn't undercut how sad her situation is.

I'm of two minds about Sarah's specialness being tied to her ability to have biological children - one the one hand, ugh, come on sci-fi get another goddamn trope, but on the other hand, producing cloned animals with the ability to breed is an actual science problem in the real world, so it makes sense that it would come up with humans. What we don't know yet is if Sarah is a surprise success story, or if all the clones were supposed to be sterile, and she's not because some guy in the lab went rogue and flipped on some genes he wasn't supposed to. (And then faked her death to get her out of the lab?) Probably the latter.

I figure we've got about five minutes before Kasima (sp?) thinks it would be more fun to be running this experiment than being a part of it.

I hope we bring Art into the inner circle soon, too. I'm not a fan of police investigations where you have someone to question right there but say "No, let's hold off on that" because the writers don't want that conversation to happen until the next ep.

Further - there was some discussion that they knew she wasn't Beth after samples were taken. How?

Guess we find out later, but I think it is related to her pregnancy.

What if John Hurt is Doctor 0...the one before John Pertwee

Do you mean the one before William Hartnell?

Also, please don't whitefont total speculation. There's no need for it and it's confusing.

One thought occurred to me - Sarah could still be the original if she was an IVF baby and they cloned the others from her at the blastocyst stage. (It also occurred to me that it's silly for all the clones to have the same birthday unless they were all born by c-section, because pregnancy doesn't work like that. 9 babies conceived on the same day aren't all going to be born simultaneously.)
