Last week, Dark Matter revealed the backstories of Four, Five and Six while teasing who might be Titch. This week, amid the excitement surrounding Ruby Rose’s guest-starring gig, Dark Matter explored how appearances can be deceiving, whether it’s an entertainment android named Wendy to a mercenary named Marcus. It all happens in tonight’s seventh instalment, when the Raza crew discovers what’s behind that locked door.

Ruby Rose shows us her kick-ass side
As expected, Ruby Rose’s guest turn as Wendy is memorable for a couple of reasons. The entertainment android—one of several items discovered behind the locked door—is gifted in the kitchen with limited food, able to deliver impeccable massages … and can perform something called Dunking the Cosmic Donut. An extended scene with One provides laugh-out-loud moments and showcases Marc Bendavid’s comic timing. Turns out Wendy is hiding something pretty big, and it has a major impact on the Raza team.

Zoie Palmer shows us her comic side
Longtime fans (or Twitter followers) of Zoie Palmer know she’s got a wicked sense of humour, and Robert C. Cooper’s script allows for some of that to shine through. Despite the fact the Android isn’t supposed to feel jealousy, Wendy’s immediate impact on the crew leaves her feeling left out. The lengths the Android goes to gain their attention again is hilarious. Two words without giving too much away: Jamaican accent.

Three shows us his soft side
I’ve been waiting to find out more info on Three and we get lots of it tonight. Among the money, guns and Wendy in the storage area is Sara (Natalie Brown, The Strain), a woman locked away in a pod. Upon being thawed out, she calls Three by his real name and recalls the man before he lost his memories, offering great insight into Three’s history and the man he can be when he’s not, you know, being a jerk face.

Two shows us her backside
Let’s just say One and Two’s relationship takes an interesting turn.

Who is Titch, and what happened in their life to turn them into a hardened criminal? That was one of the key questions posed in Episode 6 of Dark Matter.

Friday’s newest episode showcased Jodelle Ferland’s acting chops as she assumed the role of Four to give us more of his back story while we learned more about Five’s own past. With the crew of the Raza still unsure about what brought them together, Five offered up her mind to a probe in order to get answers.

We knew Four’s power-hungry stepmother was behind the death of the Emperor, but Five recounted it all for Four. We learned the Emperor wasn’t all that nice of a guy and strived to have his son feared by all despite the kind streak in the boy.

As for herself, Das realized she and the dead boy, TJ, were stowaways on the Raza. She’d picked the wrong pocket to pick and gotten her hands on that key; the man who owned it killed all of her friends and mortally wounded TJ. The two snuck on board the ship where it was revealed One and Three knew each other.

Five’s extended attachment and reliance on the probe put her life in danger, leading Six to suit up and offer to go in and pull Five back. While he sought her out, he uncovered part of his own past: his rebel group fought back against the Galactic Alliance and took the extreme measure of blowing up a space station (and 10,000 people) for their cause.

So, who is Titch? Five was involved in that person’s memories doing chores around a farm and leading a happy life when Six showed up to take her back. Five was betting those memories belonged to One, but I think it was Three. He’s just the type of guy to put up a tough front to hide some inner sensitivity. Was Three’s idyllic life shattered by violence? I’m bet that’s the case, but we’ll have to wait at least another week to find out.

Notes and quotes

• No wonder they’re running low on food. Three is eating. All. The. Time.
