Stiles is having a fun time at the police station with his dad, feeding him healthy vegetables (that’s torture Stiles! I heartily disapprove) and questioning him about the various cases. Stile’s dad can’t really keep the confidential information confidential because of the big board full of information on the wall behind him. Giving up keeping secrets, it turns out there’s one thing linking the three victims (Stiles’s mechanic, the pregnant woman and her husband) – they were all 24. And while Isaac’s father wasn’t, Isaac had an older brother who died in the military – and he would have been 24 had he lived. Stiles’s father goes from trying to keep the information from Stiles, to actively discussing the case with him (did I mention that Stiles makes this show?) Stiles points out that same age meant they went to the same class at school (then they have a gloriously little snark because Stiles’s dad didn’t spot this). Checking the class notes they find that they were all in the same class.
And one of the faces in the yearbook for that class? Is the woman selling tickets to an underground party (which Matt mentioned in passing last week). Which is where Matt is, along with Jackson acting even more odd than usual, and Scott, watching Jackson. Jackson doesn’t kill her, but it’s clearly an option for later
Meanwhile Allison and Daddy Argent (who likes to pretend he isn’t evil) are having a nice daddy-daughter day at the morgue, checking out the Kanima’s victims, while Daddy fills her in on all the stuff she already knows, the kanima, what it is, that it’s being controlled by a human. He launches into another hooray, go Argents speech, followed by questioning Allison about what she knows (that would be this matriarchal Argent society, y’see). He has the gall to suggest that her protecting her friends makes her responsible for the dead (as opposed tom her keeping secrets from her family because they’ve proven to be callous murderers? Can something please eat the Argents, now?)
Scott and Derek (and Isaac, yapping along behind them) go to see the still mysterious vet, Scott’s boss and guy who knows way more than he should, about saving Jackson (Derek still wants to kill him, I agree, but Derek concedes). There follows lots of debates about why the weregecko can’t kill a pregnant woman (because it can only kill murderers and the foetus isn’t a murderer? Because Jackson’s mother died while pregnant?) and they make the huge logical leap that since the weregecko is afraid of water and Jackson isn’t, then it must be a link to the controller (who must be afraid of water) and shows that what affects one affects the other. It’s not so much a leap of logic as a plummet of logic, as logic falls into the abyss screaming, but let’s go with it.
Mystery Vet (in case you forgot his name, like me, he’s Dr. Deaton) has some magical help to give Scott and Stiles – some ketamine to slow Jackson and some black, powdery ash that Stiles must use and ignite with his will (words cannot describe how awesome it would be if Stiles became a magic user in this series, hey I can hope). Apparently this stuff is a big supernatural ward and Dr. Deaton has used it before to keep rampaging werewolves at bay.
