When God Opens a Window: Season 5, Episode 4

This handsome kid. Mark. Poor guy, just tries to meet a pretty girl on a bus. And she ends up dead.

Mark tries to pay Bo and Tamsin to figure out who keeps trying to kill him. But all he has to offer is a watch. As Bo says, they’ve worked for less. Her sense of charity runs thin, however, when she realizes that Mark has robbed them.

Lauren drops in to chat about the serum that The Morrigan commissioned, as well as to get funding for a new security system.

Tamsin and Bo really are having a hard time getting their swerve together, when it comes to their working relationship, and also they’re pretty mad at Mark for stealing from them.

Bo’s shoulder wound from the arrow (meant for Mark) just won’t seem to heal. No matter how many times she fools around with Tamsin and tries to suck her chi.

Vex has come to warn the gang about three dead humans who have turned up nearby. But is he up to his old tricks? Can anyone ever trust Vex again?

Lauren removes a living mineral out of Bo’s shoulder, the equivalent of Fae kryptonite (hence why Bo has a hard time healing via sucking someone's chi), and acting as a tracking device for Bo.

As Mark decides to help Bo heal in the way only Bo can, the hunter turns up and starts causing a good deal of trouble. As expected, Bo handles it with her signature brand of ass-kicking and the hunter becomes the hunted and ends up in captivity.

It turns out that the hunter is trying to avenge his family: Mark and all of his kind killed his wife and daughter. When Bo asks him to tell her the truth, she realizes he’s telling the truth. But of course, Mark denies the whole thing.

When Vex, Dyson, and Lauren put the clues together about the three dead bodies that went missing from the morgue, they figure out that what they’re dealing with is a fae cult.

Bo sort of can’t help herself, she sleeps with Mark and finds it all very restorative until she realizes that he has, for the third time now, stolen some of her stuff and made off into the night. He’s handsome AND wily, that kid.

Wait! Quick interlude! There she is again, that blonde woman, who seems to be drinking the blood of dead humans. Is she the leader of the cult!?

Turns out, Mark is Dyson’s son! Didn’t see that coming! The hunter has been tracking them ALL down, because he’s basically a werewolf hunter. That’s the danger that Dyson has been feeling all day!

Also, the Morrigan brings a pretty terrifying beast by and drops it off with Lauren as part of her payment for not yet having a serum.

And as expected, Dyson kills the hunter in order to protect the only family he realizes he’s ever had – Mark.

And then he tells Bo that Mark looks up to her. Like a sister. Ew. Gross. And also, whoops! Probably shouldn’t have slept with him, but has that ever stopped Bo from sleeping with anyone?

And yet, the gang seems to be overlooking the fact that something evil, blonde, and bloody seems to be on the horizon.
