I'd wanted to originally blog about each episode, but I didn't because I'd gotten all into the story. It's not too late to start, though.
Nick investigates a robbery that leaves a spice shop owner and wesen--a Fuchsbau named Freddy Calvert--dead. Previously, Nick had a run-in with Freddy who'd been working with gaiers to provide other wesen a unique service. Nick had let Freddy off with a warning that he needed to give up his illegal product. At the scene of the crime, Nick worries that Freddy might've gone back to selling his illegal merchandise, which could've factored into his death, but finds no evidence that he'd done so. Nick learns about a legal substance that is deadly to humans but wesen use it to get high (Monroe compared it to crystal meth) that Freddy stocked.
Meanwhile at a museum, Captain Renard and Adalind are discussing plans about how to get to Nick. We still don't know what they're trying to do to Nick, and Nick is completely unaware that his boss is a wesen. Renard suggests that Adalind use Nick's friends against him, specifically Hank, telling her to do whatever is necessary to snag him. Adalind bakes Hank cookies using a mixture of her blood and his blood, which causes him to start developing an obsession with her when he eats them.
