OK, the stuff with Alison's husband, Donnie, speaking at the intervention was partially played for laughs (not the part where he talks about their kids, but most of the stuff before that).

It was refreshing to see a cop in a fictional show zoom in on a video frame without also "enhancing".

Even though they haven't actually solved anything yet, I think that the Toronto "Metropolitan Police" homicide department have done much more productive police work in this one episode of Orphan Black than the Miami Metro Police homicide department have during the entire run of Dexter.

How even Sarah figured that one out is left as an exercise in the imagination of the reader.

I thought the same thing when I watched this episode.  Wouldn't she need to swipe an access ID card to get in?  Wouldn't her computer be password-protected?  The Toronto "metropolitan" police service on this show has worse security than Miami Metro on Dexter.

I don't think I'm being the Comic Book Guy here.  I'm not sitting at home watching the show and saying, "Worst show ever!  I clearly heard that gun fire 7 times but that model only holds 6 rounds.  And the same xylophone key was struck twice in succession but produced two different notes!  And they referred to their…

Beth was supposed to be Canadian, like Alison and most of the other characters on the show are. Presumably, because I think they were brought over by Mrs S as teenagers or younger, Sarah and Felix would be naturalized Canadians. Cosima is supposed to be American.

If they're clones of any original person, there's no reason for them all to be sterile, any more than the original is.

I really hope that one of the clones we have met is not actually "the original", because that's not how cloning works!  I realize this is just a show and I really should relax, but I will be mildly disappointed if the show goes that way.

Even if we’re not in for the Virgin Mary situation, though, we're definitely in for a heavy dose of religion, which I guess was inevitable in a show about clones.

I took note of a few Canadianisms from the show, since "where is this set" is still a question that I see online, as of the third episode, at least.

I'm embarrassed to say that I noticed that they kept calling the one police guy "lootenant" instead of "leff-tenant" (which is the Canadian way of pronouncing "lieutenant"), but I didn't even clue in to the fact that Canadian police services do not have any rank called "lieutenant" until you pointed out that they are…

I don't think we saw the French one, but in the second episode when Sarah was looking through the papers in the briefcase, I think she mentioned a bunch of other ones, one in France, one in Italy, etc.

That's a good point.  Although, in that sense, being the "first" clone isn't really anything special if it just means she is a few weeks older.  It doesn't make her the "real" one.

Identical twins' fingerprints are similar but different enough to be distinguished. See
Twins and Fingerprints from the NY Times.

It is true that identical twins (nature's clones) do not have identical fingerprints - they can be distinguished.

I also liked how Sarah was so freaked out and shaken up after they just got shot at, Art got hurt, and she was expected to chase an armed and dangerous person.

If Killer Clone is the first clone…

I did groan a little when his first reaction to babysitting Alison's kids was to ask the boy if he wanted to dress up as a girl, but watching Alison's horror as he swanned out of there was pretty great.

I am pretty sure that cops in Canada cannot enter a residence just because a motorcycle that might be stolen and might have left tracks at a murder scene is outside and the landlady says it belongs to the person who lives there, and the cops see motorcycle gloves through the window. There’s no way that can be enough…
