SPOILER ALERT: Please do not read on unless you’ve seen the Season 3, Episode 8 of Orphan Black, titled “Ruthless in Purpose, and Insidious in Method.”

Orphan Black episodes like this week’s bring to light just how remarkable Tatiana Maslany is. We almost take it for granted now, that the manic laughter of Helena, the tepid murmuring of Cosima, the dastardly side-stare of Rachel, the uptight cleanliness of Alison and the dark edge of Sarah all come from the same person. When you think about it, it seems insane that a show can be as engaging, as interesting, with one actor as the crucial centrepiece.

And of course, was playing a new clone (who we saw before, briefly, at her encounter with the Castors): Krystal Goderich. In her push-up bra and blonde hair, Krystal is instantly memorable and pretty much exactly how Felix describes her—as Sarah would be if she went to college. Maslany plays this character so easily, like Krystal’s been on the show since the beginning.

Jordan Gavaris also got a turn to shine, and it’s been a while since we’ve gotten a chance to see his chops, which I recall from Season 1. (That’s CHOPS, not CHAPS.) He was woefully underused in Season 2. Finally we’re freed from boring housebound Felix, and we’re treated to hardcore street punk Felix. When he slapped on the headset and spoke in his straight Canadian man accent to Krystal, it was one of my favourite Orphan Black moments to date. This is the fun stuff, this is the kind of thing fans are after.

Same goes for the Cosima/Shay/Delphine plotline, as many fans have a lot invested. I’m actually strangely invested myself, probably a testament to the realistic relationship being portrayed. OK, so it involves a clone, a progressing mystery disease and a multinational conglomerate, but I mean the emotions and the dialogue, guys. When Delphine and Cosima kiss, in my head I could hear “No! No! Don’t cheat on Shay!” and silently cheered when Cosima backed off. But at this point, we obviously can’t trust Shay. She’ll end up being a spy and then Cosima will get back together with Delphine. With all this talk about death and near-death experiences, seeing Delphine in a light … makes me concerned that Cosima will die in the end with Delphine by her side. Food for thought.

Even the Alison/Donnie plot is getting darker. Now Jason is very much a threat to their marriage, and it’s apparent that Alison is barely hanging on to her convictions. I gotta hand it to Donnie, he tries to get in there. He’s beaten to a bloody pulp, but at least he attempts something. I personally can’t wait until the drug-dealing scheme is over. Take the money and run, Hendrixes.

Of all the main characters (Maslany played six of them tonight), Scott got the s**t end of the stick. I have grown quite fond of the gentle nerd over this season, with his real estate fantasy board games and extensive sci-fi book collection. Not only does he get held up by Rudy, he loses the Island of Dr. Moreau, has his co-plan foiled and then loses his job. Oh no, wait. Krystal gets the s**t end of the stick if they’re doing what I think they’re doing, which is taking her eye for Rachel and then keeping her for tests/as a Rachel replacement. Yeah, that’s far worse. I hope she doesn’t die, she would make for an interesting character going forward. Things are looking sour for everyone, and judging by clips of the next episode, they’re going to get worse before they get better.

Off to London next week. Cheerio!

Clone of the Week: This is a toughie. I’m going to have to say Krystal. She was engaging (more than likely because she’s new), and it always fascinates me how Maslany wraps herself around these roles.

Random Thoughts:

• Emmy submission! Globe submission! Seriously, I know sci-fi is an underrated genre, but c’mon six very different characters—often more—in one episode? Is that a world record?

• Did I hear mention of a Polish clone? Sigh. That is just wonderful.

• Felix: “Did I just get seconded into this s**t?”

• Shout-out to the Firkin on King! Drank there many a time.

• LOVED that shot of Rachel looking through the magnifying glass with her good eye. There were actually a ton of good shots tonight, but this one particularly stood out.

• Krystal: “Bitch Mistress Cums-a-Lot.”

• Helena + Gracie, co-workers, friends for life.

• Delphine: “I’m French. We enjoy lovers.”

• Rachel’s “top speed” in her wheelchair. I totally appreciate these quick quips you throw in there, writers!

Orphan Black airs Saturdays at 9 p.m. ET on Space.
