Amanda Tapping went crazy on last night's episode of Sanctuary — and not just because she stepping into the director's chair. It's all linked to a conspiracy within the Sanctuary Network, and one of the most destructive abnormals on Earth.

Last night's episode began with what was supposed to be the ultimate Sanctuary shocker: Bigfoot turns up dead in the Sanctuary's morgue. I can't imagine that we're supposed to believe for a moment that the Big Guy is actually dead; he already almost died once this season, and it's unlikely he'd get such an ignominious demise without some sort of build-up. But then there's the kicker: Declan Macrae (a character I constantly forget is on this show) believes that Helen Magnus murdered the Big Guy. Macrae, who's more than ready to hop in as head of the Old City Sanctuary, claims that Bigfoot discovered that Magnus was suffering from a degenerative mental disorder and that Magnus decided to silence him, permanently. Of course, Will is having none of this and, after shedding a few requisite tears for the Big Guy, launches an investigation to prove Magnus' innocence. It doesn't help matters that Magnus is increasingly batshit insane and that there's a video of Magnus actually shooting Bigfoot. By the time the Triad, a group of psychic interrogators from the Sanctuary Network, show up, Will is completely at a loss.

As it turns out, though, Magnus really is crazy — crazy like a fox. She's out to expose the Triad members, who are after Big Bertha, an abnormal capable of leveling whole cities. And why might the Triad want to get their mitts on such a creature? I'll let the lovely Erica Cerra (who's really been making the rounds on Syfy shows this year) explain above.

I definitely perked up at the description of Big Bertha. Tectonic plate-shifting abnormal? Yes, please. We may have had our zombie apocalypse a few episodes back, but we've never seen a single abnormal on such a large scale. I was looking forward to seeing Big Bertha, even if it was just a little glimpse. But sadly, Big Bertha was just a cataclysmic tease, and when Cerra's Triad member opened the shipping container that allegedly held her, there was nothing inside, nada. Instead, we were treated to a breakdown of just how clever Magnus' plan to expose the Triad was. Shooting Bigfoot with a paralytic chemical? Ah yes, very clever. Placing an insanity-inducing beetle in her brain so she could hide her true thoughts from the Triad psychics? Uh-huh, brilliant. Coding a message to Kate so that the team could snare Erica Cerra in Magnus' trap? Yes, we get it, Magnus; you're a genius. But I'm still miffed we didn't get our big earthquake-maker.
