Damn. Great finale. Painful wait for next season.
Who is Mrs S? I'm guessing she has some involvement with the Dyad Institute and then she went rogue and somehow arranged for at least one of the clones to fall into her care. It would appear that she's now on the run from Sarah and the Dyad Institute judging from the trashed house, although I guess she could have trashed the house just to keep Sarah guessing about what is going on. Still, it was stone cold of her to run with Kira.
What is with Paul? I'm still unsure what the Dyad Institute have over him. I thought we'd seem pictures of him beat and being held hostage somewhere. But he told Sarah that he was a "private contractor" who accidentally killed six American soldiers in "friendly fire". Would a private contractor, presumably there to do construction work, really carry a gun and use it to kill six people? Maybe I missed what his explanation was, but it seems as though he's still lying to Sarah as well.
Donnie is Allison's monitor! It makes sense since they never explained his odd phone conversation while burning the contents of his lock box, but it was still a bit of a shocker. Not as shocking as Allison killing Ainsley! The Desperate Housewife has really changed over the course of just eight (?) episodes since she was introduced.
Poor Cosima. Dying from whatever affliction Katya had. I hope Delphine isn't playing her, but I suspect that Delphine is still loyal to Doctor Leckie. If he has agents/soldiers who are willing to enter into extremely long term relationships with clones for the sole purpose of scientific research, then I find it hard to believe that Delphine would be so easily swayed by Cosima's love. We knew that Paul was messed up before Sarah impersonated Beth, but there was no indication that Delphine has been anything other than a loyal employee (and lover) of Dr Leckie.
And is Helena really dead? That clone has taken serious punishment before and bounced right back (similar to Kira and her ultra healing). Unless Sarah put a second bullet into Helena's brain, I have to wonder whether she will return to her "sister" next season.
Orphan Black has easily been my favourite TV series in 2013. I'm surprised by just how good it is and still amazed by the lead actor's skills. The Helena impersonating Sarah scene was brilliant. There was something "off" about her posture or body language which indicated that it wasn't Sarah, but it wasn't obviously Helena either.
