Of all the possible reveals I’ve been anticipating and speculating about for Lost Girl’s final season, Dyson turning out to be a long-lost baby daddy was not one of them. Although given Dyson’s possible turn from the Light side, maybe this is setting up some final saving grace for him after killing The Hunter (Aaron Poole, Strange Empire) in cold blood.

After the first handful of episodes were easily making this season out to be all about Bo and her search for her father, “When God Opens a Window” seemed to be taking advantage of the extra episode order by giving us an intriguing look into Dyson’s psyche, post-Season 4’s devastating loss. And judging by his grand speech to the unpleasantly returned Vex and his bloodstained face as he nursed a beer and some memories, things have gotten—dare I say—Dark in Dyson-land.

While it seemed like a pointed reminder to Trick to get him back for sticking Vex with Dyson, in hindsight the wolf’s comments about whom he’d sworn fealty to now have more weight. Was Dyson aware he was struggling with being the good guy when he made that oath, or has doing it finally given him the freedom to act on certain urges? Either way, it’s now apparent Dyson’s allegiance to the unaligned Fae in his life is going to be having an effect on him—especially since Bo clearly knew where the blood was from and didn’t confront him about it. And maybe that’s a good thing, looking at the generations of fighting between The Hunter and the Shifters. Moving away from binaries, traditions and old grudges could make for a much healthier Fae world.

Though I’d feel much better if this ended up being Dyson’s only major transgression—mildly justifiable since The Hunter wasn’t all that good himself. As refreshing as it is to see Dyson take a break from his constant do-gooder ways, now might not be the best time for him to totally descend into evil even if it could make for some interesting relations between Dyson, Bo and her father. Of course, if Mark does end up hanging around, there’s always his own path to redemption by hopefully helping Dyson instead of simply living up to the retelling of Vex’s paternal relationship with Massimo. Forgiveness is all well and good from parents, but as we’ve already learned multiple times this episode between Vex and The Hunter, there are serious consequences to those kinds of actions, however much daddy may love you.

Then again, given Bo’s particular allure for Dyson’s son and the awkwardness it immediately brought on, maybe it’s best if Mark takes off for a bit. In between Tamsin edging in eagerly to help Bo heal, her no strings arrangement with Dyson and the lingering tension with Lauren, I’d say Bo’s got her hands awfully full even if she is a succubus. And after that whole stepmom debacle, I don’t now how much more keeping it in the family I’m interested in seeing.

Besides, as much as shipping has become a fun part of the show, at this point I’m far more excited to find out who our elevator lady is, what that lighting she apparently commands is, and especially what another triskelion is doing on a supernatural show (having been a go-to design for Teen Wolf since the beginning). While the symbol Dyson put together apparently fits a more Celtic look, I’m still anticipating the connection of Persephone and Artemis via the candle to mean we’re headed for a much more Grecian revelation. And if that’s the case, I think it rules out Walsh as Demeter, if her behaviour hasn’t already. Though we may have at least some part of the mystery in our hands now after Evony dropped off a very, very old evil at Lauren’s lab—wasn’t that what we were looking for last week?

“Strong, merciless, vulnerable,” were the words Bo used to describe a good leader in Sunday’s Lost Girl. While the episode may have only touched on the big mysteries unveiled last week as Bo and Tamsin took on a case of the week, in the end Musashi’s story did feed into the season’s bigger arc as Bo questioned what being the Chosen One meant for her and those around her.

And it was the vulnerability aspect that was most important in “Big in Japan,” not just for Musashi and his faux-claim to fame, but for Bo who was coping with Kenzi’s departure in obvious (see: decorating) and less obvious (see: not taking in chi) ways. While Bo may have been able to spot Musashi’s resistance to embrace his own vulnerabilities, in the end it was Tamsin who had to force Bo to confront hers—a nice parallel that ended up moving Bo’s evolution along in an episode that original seemed like it was going to kill time with a case of the week.

For all her bravado going into hell, confronting what may have been the arm of her father and coming back out (with the world’s worst candle) Bo’s challenges this season look like they’re going to be delving into the most personal, and possibly fragile, parts of her life. The show has already alluded to her father’s dark nature and a big part of what’s to come for Bo must be accepting whatever influence that has had on her without letting it define her. But as she pointed out, being who she is has also already cost her plenty and taking time to acknowledge that loss, especially in the face of losing Kenzi, is rightfully another part of her role she has to live with. Though what makes Bo a better leader that Musashi just might be her willingness to see leadership, and its cost, for what it really is and not just the glory of a bar full of Fae wanting to be like her.

Although—and maybe it’s blasphemous to say this—it was pretty fun to see Tamsin helping Bo with this week’s case and stepping into that empty spot next to her. While nothing could replace all of Bo’s years with Kenzi, those heartfelt moments in Lauren’s surgery were a good reminder for Bo that she’s still got plenty of friends with her. And while Tamsin may have a number of strikes against her, she rightfully got recognition for knowing a bit more about her roommate than she’s been given credit for. I expect she’ll been taking Dyson’s suggestion that she leave the shop and join the family business pretty soon, if not in the coming week. Though with this season set to deal with daddy dearest, I don’t know how much time they’re going to have to take cases—even if they do fit as neatly into the story as this Sunday’s.

It was also another week of Dyson and Lauren teaming up with their sass providing a nice counterbalance to all the flirtatious teasing going down between Bo and Tamsin (the writers are just playing with us, right?). There’s a bigger sense of the stakes the season is building towards whenever these two talk since their main common ground at the moment is Bo and how to help her survive what’s coming. Given their flirt-free zone, I’m actually digging the friendship between these two since Dyson’s down a buddy, and the combination of Dyson’s training and Lauren’s science-savvy made for a pretty sweet takedown of the first Fae to come for her.

Though Lauren might need more than her wrist and some ketamine if elevator-lady is still in the lab when Lauren returns to work because I’m getting the sense—from the maniacal face, resurrection stunt and neck snapping—that she’s not your average baddie. I guess the question we’re left with, aside from last week’s “who is she?” is whether she’s very, very old or really new. Any bets?
