Things are certainly heating up on Lost Girl—and I don’t just mean that surprise hook-up between Bo and Tamsin, although it does feel like this week’s biggest development. Rookie Blue’s Noam Jenkins made his first move as a resuscitated corpse, bringing the ominous words “beginning and end” to screens and teasing something cataclysmic in the offing.

Considering how long things between Bo and Tamsin have remained at the casually teasing phase, I was pretty stunned to see Tamsin finally make a bold move—and, admittedly, even more surprised to see Bo, after a moment’s hesitation, opt for the second of Tamsin’s gifts. Maybe it’s because their friendship has been so rocky, or maybe because I was sort of digging the banter-creating tension between them as they started working together, but I’m not entirely sure how I feel about these two launching into something that looks like more than a chi-swapping fling.

I guess that for all the hints and chemistry between the two, I’ve always assumed Lost Girl would head to some kind of resolution involving the Bo/Lauren/Dyson triangle—though maybe this move is suggesting the show is considering something a bit less predictable for our loving fae and her friends. Either way, it gave Bo someone to confide in, and I can’t think of anyone who would be more understanding about Bo’s need to separate herself from her father’s legacy than Tamsin.

And while I’m certain that whatever’s brewing with Lauren and Dyson’s elevator crash case is closely tied to Bo’s father—both did, after all, begin with a trip to Hell and one cryptically named candle—I’m guessing that final shot of Horatio, a.k.a. the recently-deceased Kevin Brown means solving the elevator crash might take priority over that rune-covered Jack-in-a-box present from daddy dearest.

It’s certainly more pressing for the fae world now that their signatures—and powers—have been taken from the safety of Trick’s lair and are now being used by Kevin, and, presumably, that mysterious blonde woman responsible for his death, to hunt for whatever fae they need to take out (or collect pieces from). With the oracles now blind to any other visions, there’s no one to warn Bo and the rest about what’s coming, or what it may want from the rest of the fae.

Except maybe Dyson’s new kid, Mark, if he somehow manages to get over being a ridiculous stereotype of a teenage brat in time. Right now it seems like he’s on his way to being recruited to the Dark side—a process Dyson should probably explain to him a bit more clearly, and soon. Because while the kid’s aware his new friend stole the book, he doesn’t seem to have any idea what that means, or why it’s important. And sure, he’s dreaming Bo’s dream of being unaligned, but right now I don’t think he’s savvy enough to pull that off. Especially since Vex seems to be the only friend he’s capable of making, and I wouldn’t be surprised to find out Vex is the one who orchestrated the whole hook up in the first place. Mark’s recklessness may have been cute enough for Bo last week, but it’s quickly turning into something dangerous. And if Dyson doesn’t step it up in the paternity department soon, there may be more problems than a few broken pint glasses.

And as fun as it was to watch Tamsin deal with Bo’s slow transformation into a kitten (note: a napkin is not a suitable cover for the sudden appearance of paws), or to at least watch Anna Silk take up residence in the soothing confines of a cardboard box, I’m still itching to make a bit more progress on what the hell (pun intended) is going on with, well, everything. Or at least see the team start to connect a couple of the dots and give us something a bit more substantial to speculate with.

Lost Girl airs Sundays at 9 p.m. ET on Showcase.
