Bo is mistaken for the arriving help, and learns that Valkyries are serious about who they let into Valhalla. It's run by a woman named Freya, who sort of dresses like a debutante. Which really mixes with the whole Norse mythology thing, no?
It turns out that the hell-shoes are capable of allowing the wearer (Bo) to summon a dark army capable of destroying all life on Earth. Oh. That’s not good. So Lauren and Dyson try to figure out how to get that message to her.
After Kenzi learns that this is probably her version of heaven and she’s about to marry Hale, she’s confronted by Tamsin – who is seemingly possessed and under orders by dude on the phone to collect Bo's soul.
Freya drops the bomb that Kenzi's been promised to creepy-dude-who-called-Tamsin, who lives in anothe realm. Bo strikes a deal with Freya to take her instead of Kenzi, who Bo also gets returned to her corporeal body.
So who do we think the Valkyries are coming after. Dyson? Lauren? They try to open a gate to Valhalla, but Lauren ends up getting possessed or something before passing out. However, she does learn Kenzi's been sent back to Earth.
