It did dawn on me later that perhaps you meant the writing in the article, not the show but without clarification, I thought I couldn't rule out taking it either way (though the more I thought about it, the more I thought the way you meant was what you've clearly said you meant) .

To add though, it's not a Category One Sophie's Choice. In that case, Sophie was equally pulled between her son and daughter. In this case Felix had more of an attachment to Sarah and went that way but there still would have been some pull towards Alison as well.

Catch-22 incorporates the mutual exclusion principle and is a condition that is physically impossible to achieve due to it's inherent intrinsic contradiction within itself.

I was obliquely making that point myself with the "geographical order" remark. As easily distracted as I can be, it hasn't escaped my attention that Helena isn't the most rational of actors.

I knew about Situs Inversus beforehand, having written about it at great length in this comments section and even seeing it in real life. I didn't know there was a term specific to twins though, which is Situs Viscerum Specularis, which I learned from the message boards of Chud dot com of all places.

I've already expounded on this at great length in this section but I have always wondered where this misconception comes from. Apologies for event mentioning this, if you look at the video for the song Heartbeat by Enrique Iglesias and Nicole Scherzinger, for some reason they have the heart sitting way off in the…

I hope I'm not out of line, being that you're a Pop Culture Reference and all but that's not a Catch-22. It's a Sophie's Choice.

An even more terrifying observation by someone in the comments at io9 is the possibility that the insemination scene and the debate about whether Helena could become pregnant or not between the Prolethians was potential foreshadowing of the most sinister kind. I'm already hoping Helena lays waste to them but if they…

Even more fun with science for anyone who is interested:

Even scientists with a fraction of Cosima's experience (or medical students for that matter, let alone doctors) would know that Rachel all but said nothing in medical terms. It really was that broadly vague in scope.

As for Mrs S's "Bulletproof Care", that time when she didn't notice Kira had walked out of the house at the time it happened and Kira ultimately getting run over notwithstanding, of course?

I never took it as Rachel being discriminatory or disapproving. It's just that it totally came across as "Thank you Captain Obvious".

Mirror imaging of the fingerprints of identical twins doesn't happen that often, it's only a minority of cases. Also it's not a perfect reflection for the same reason identical twins without mirrored fingerprints aren't the same, gestational and environmental factors during development.

That's a good point, I didn't think of it that way. However that would have tipped all of them off (before then they didn't know for sure they were being hunted, as Cosima said) and risked pushing them all underground and making them even harder to find after that.

I was just trying to think of something firearms related. I'm sure there was a perfectly logical explanation like Helena was working in geographical order and couldn't start taking out all the Canadians until after she'd finished off the Europeans or something like that.

We have to give some leeway for some things for the sake of the story I suppose. For example, I haven't been to sniper school (not yet anyway) but I would have thought that when Helena had Katja and who she thought to be Beth in her sights and they had no idea she was there, it would have made the most sense to take…

If anyone was wondering what the significance of Rachel telling Cosima that she had a "High ESR, high CRP and raised leucocytes" could mean on its own without any other clinical data is that in theory, she could have just about any infective process and a wide range of other inflammatory processes.

The dates of death written on Cosima's Clone Chart back in episode 1.08 is one place. All the Euro Clones and Beth are shown to have died in 2012 (she used the YY-MM-DD format).

Short Time was a great flick. Glad someone remembers it.

That was already a given.
